Privacy Policy
JOAJO Rent a Car safely protects your personal information and strictly complies with EU GDPR regulations.
1. Personal Information Collected & Collection Methods
We collect the following minimum personal information necessary for service provision.
- At booking: Full name (Korean/English), email, phone number (or KakaoTalk ID)
- At a Prague quote request: name in Latin letters, date of birth, email, phone number, KakaoTalk ID (optional), rental dates and times, pick-up and return locations (accommodation name and address), number of passengers and bags if you ask us to recommend a car, requests
- When you save a trip to your account: trip name, stops and number of nights (and the location of any point you marked on the map), and the pick-up and return points if you chose them. They are deleted together with your account.
- At vehicle pick-up & identity verification: Driver's license number and type, passport number. If we check your identity with our identity verification service (Didit), Didit reads your ID document. In our Didit settings, comparing the photo on the document with a face captured by the camera during the check is switched on, so the result may include a face match score. The information we receive from Didit may include the result (whether you were verified, the face match score, warnings and, for checks done in the app, the result of reading the document's chip) and the details read from your ID document (name, including any non-Latin spelling, date of birth and age, sex, nationality, place of birth, document type and number, personal number, issuing country, date of issue and expiry date). Of this, we keep only whether you were verified and the issuing country with your booking, and we include the result and the document details in our staff notifications (Telegram, see 4-2). We do not store any other part of this information in our database. Before this amendment, the result details were also written to our server logs; those logs are deleted automatically within about 30 days of this amendment.
- At advance driver registration (document photos): a photo of the passport photo page or of the front and back of an EU national ID card, photos of the front and back of the driver's license, and – for non-EU licenses – photos of the cover and photo page of the International Driving Permit (IDP)
- Credit card/payment info: Online payments are processed by Barion Payment Zrt. Card data is handled exclusively on Barion's PCI DSS Level 1 certified secure servers. We do not store or have access to your card information.
- When you log in (Kakao or Google): the email address the login service gives us (for Kakao, only if Kakao has verified it), your name or nickname, the link to your profile picture (Google), and your member ID at the login service
- Corporate inquiries: company name, contact person's name, email, phone number, the number of cars and rental period needed, and your message. To block automated submissions, this page uses Google reCAPTCHA, which sends device, browser and page-interaction information to Google.
- When handling traffic fines and tolls: the information in fine notices or driver-identification requests sent by the authorities (license plate, date, time and place of the offence, amount and, where included, the driver's name, address and driver's license number)
- When you use the website (our own statistics): the pages you visit and their order, the booking steps you reach and the time spent on each, your search details (dates, locations, car and quoted price), clicks on the contact buttons, how often you open the chat window on our website, when and on which page you first open it, which question, link and contact buttons you tap in it, how many questions you type and send, how often you rate an AI answer, and how often it fails to load or to get an answer (these statistics do not include the content of any question; for the chat window's conversation records, see the chat assistant item below), how you reached us (referring site, ad campaign, Naver search-ad keywords), device type, screen language and time zone. We do not put your name, email address, phone number or IP address in these records. Only if you click Accept in the cookie banner, a random visitor number stored on this device links your later visits, and when you complete a booking on the website, the visit record is linked to your booking number. Without your consent, the records are only linked within a single visit. When you book on the website or request a Prague quote, we also store how you reached us (including the referring address and search terms) with that booking or request; ad click IDs are stored only with your consent.
- When you use the chat assistant (the chat window on our website): your question and the answer shown to you (unmasked, as written; each question up to about 2,000 characters), the time of the question, the screen language and the type of page you were on, kept as conversation records. Questions the chat assistant could not process (for example because of usage limits, because the question was too long, because AI answers were switched off, or because of an error) are kept in the same way; however, if an unusually large number of requests arrives in a short time, some of the questions that could not be processed are only counted and their text is not kept, and questions that never reach our servers (for example because the connection dropped) are not kept. Opening the chat window, starting a new conversation, sending a question (without its text), the buttons you tap in the chat window, the links and contact buttons (KakaoTalk, WhatsApp) you use, your ratings of AI answers and the guidance cards shown to you are each recorded, together with the time, the screen language and the type of page, for each conversation under a random conversation number; these records contain no text and no personal information such as names or contact details. We also process your IP address for usage limits (we do not store the address itself, only a value derived from it with a secret key we hold; for the records our servers keep automatically, see "Server access logs" below). What is sent to the AI and how long it is kept are described in 4-3.
- Preventing abuse of the service: your IP address when you use features such as booking and change requests, booking look-up, submitting driver details and documents, return photos, Prague quote requests and payment links (used to count how often they are used within a short period and to check for misuse; when a payment link is created, the IP address is also kept in our server logs and in the Barion transaction note)
- Server access logs: records our servers keep automatically when you use the website's server functions (IP address, time, requested address, browser information, and processing details such as booking numbers and the recipient addresses of emails we send)
- Error reports: if an error occurs on a page, the error details (including where in our code it occurred), the type of error, a random number created each time a page is opened, the address of the page (without the part after "?" or "#") and browser information. Some records saved before this amendment still contain the part after "?"; they are also deleted within the period in section 4 (90 days).
Document photos are used solely to verify driver qualification and identity, to perform the rental contract, and to satisfy insurance and legal requirements (legal basis: Art. 6(1)(b) and (c) EU GDPR). They are stored in strongly encrypted Google cloud storage located in the United States (see 4-2), no public internet link to them is ever created, and only authorized staff can view them. They are not shared with third parties and are never forwarded via messengers or email.
2. Purpose of Collection and Use
Collected information is used only for the following purposes.
- Vehicle booking, cancellation, and rental/return processing
- Driver qualification verification for insurance purposes
- Booking-related email notifications and emergency contact
- Checking and confirming Prague round-trip quotes and arranging the rental with our partner Express Rent (including checking that the driver is at least 26)
- Login and account management
- Responding to corporate inquiries
- Handling traffic fines and tolls, and answering driver-identification requests from the authorities
- Improving the website and analyzing the booking process (our own statistics)
- Answering rental questions in the chat assistant, checking the quality of its answers and what we told you, and preventing misuse of the chat assistant (see 4-3)
- Running and securing the service, fixing errors, and preventing abuse such as automated or excessive requests
3. Cookie & Local Storage Policy (EU GDPR / ePrivacy Compliance)
Without your consent we only use the local/session storage required for the booking process, system security and the features you ask for (the trip you are building and the trips you save on this device in the trip planner, the inspection checklist, and the conversation in the chat window on our website and its conversation number, which are kept only in this browser tab and deleted when you close it; questions you type and the answers to them, and the record of what you do in the chat window and the guidance cards shown in it, are also kept on our servers as described in 4-3), the Barion cookies that serve payment fraud prevention (see 3-1), and our own visit statistics and reCAPTCHA described in the next paragraph.
Our own visit statistics and reCAPTCHA: regardless of your consent, our own visit statistics (section 1, "When you use the website") use session storage to link records within a single visit. We store a random visitor number on this device (local storage) to link later visits and bookings only if you click Accept in the cookie banner; if you reject, we delete the stored number. On the corporate inquiry page, Google reCAPTCHA runs without consent to block automated submissions.
Only after you accept in the cookie banner do we place optional cookies: Google Ads / Google Analytics (ad measurement and statistics), Naver search-ad conversion tracking, and the marketing use of data by Barion. You can change your choice at any time under "Cookie settings" in the footer; the banner is shown again at least every 13 months.
Map display: when you use the trip planner, map tiles are loaded from OpenFreeMap (delivered through the Cloudflare CDN), so OpenFreeMap receives your IP address.
Place search: when you search the trip planner in Latin letters, we use the Photon place search by komoot, so your search text, the map position (the map centre, rounded to about 1 km) and your IP address are sent to komoot.
External fonts, images and videos: the website's fonts are loaded from Google Fonts, so when you open a page your IP address and browser information are sent to Google. The video preview images on the home page are loaded from YouTube (Google), the flag images in the vignette guide from flagcdn.com, and the logos on the login page from Google and Wikimedia; your IP address is sent to each of these providers as well. If you press play on a video, the YouTube player (youtube-nocookie.com) opens, and from then on YouTube may store data on this device.
3-1. Barion Smart Gateway (Payment Fraud Prevention)
Our website uses the Barion Smart Gateway service for payment fraud prevention. The Barion Pixel may collect the following data:
- Browser data (type, version, language, screen resolution)
- On-site activities (page views, clicks)
- Transaction identifiers and payment status
- IP address (anonymized)
- A one-way hash of the email address and phone number you enter in the booking details step
Data processing is solely for the purpose of preventing and detecting payment fraud. The legal basis for processing is Art. 6(1)(f) of the EU GDPR (legitimate interest). You can review Barion's privacy policy here: Barion Privacy Policy.
Cookies set by the Barion Pixel: ba_vid and ba_sid (essential, fraud prevention, work without consent) and BarionMarketingConsent (marketing). If you click "Accept" in the cookie banner, Barion may also use anonymised browsing data for marketing purposes. You can withdraw this consent at any time by clearing this site's data (cookies and storage) in your browser, after which the banner is shown again. The banner is shown again at least every 13 months.
The payment service provider is Barion Payment Zrt. (Registered office: H-1117 Budapest, Irinyi József utca 4-20, 2nd floor, Company reg. no.: 01-10-048552). Barion Payment Zrt. is regulated by the Central Bank of Hungary (Magyar Nemzeti Bank), license no.: H-EN-I-1064/2013.
4. Retention and Disposal of Personal Information
JOAJO Rent a Car securely stores your information using Google's top-tier cloud infrastructure with strong encryption.
Once the rental purpose is fully achieved (vehicle returned) and any legally required retention periods end, personal information is immediately deleted or securely masked (***) to prevent identification.
The following records are deleted after a set period:
- Visit records from our own statistics: deleted after 90 days; only daily totals are kept.
- Server access logs: deleted automatically after about 30 days.
- Error reports: deleted within 90 days.
- IP address records for abuse prevention: deleted from our database within 3 days of your last use (for backups, see below).
- Chat assistant records: conversation records (including the record of what you do in the chat window and the guidance cards shown in it) have no set deletion date, are deleted at your request and can be viewed only by our administrators; the records used for usage limits are deleted from our database within 3 days of your last use (see 4-3; for backups, see below).
- Staff notification chats (Telegram) and booking management spreadsheets (Google): no automatic deletion period has been set; we keep them for as long as we need them for our work. If you ask us to delete your information, we handle the request as described in section 5.
- Backups: for disaster recovery we back up the whole database every day and keep each of these backups for 98 days (in the EU), and we also make a daily file backup of the data that we keep for up to 31 days (in the United States). Information we delete (including information deleted at your request and the IP address records for abuse prevention) may therefore remain in backups for up to 98 more days before it is deleted automatically. Files deleted from our file storage (such as document photos and expired file backups) remain recoverable for 7 days before they are erased. Backups are used only for recovery.
4-1. Disclosure to a Third Party (Prague partner: Express Rent)
If you request a quote for a rental that starts and ends in Prague, we share the data below with our local partner so that they can confirm the car and carry out the rental. We share it only if you give your consent on the quote request form.
- Recipient: Express Rent (operated by Alexandr Kulichkov, Czech business ID (IČO) 07870973), Panská 894/4, Prague 1, Czech Republic
- Purpose: checking car availability and the final price, concluding the rental contract, handing over and taking back the car, and handling the rental payment and deposit
- Data shared: name in Latin letters, date of birth, contact details (phone number, email), rental dates and times, pick-up and return locations (accommodation name and address), the car you chose (or, if you ask us to recommend one, the number of passengers and bags), and your requests
- Retention: until the rental contract has been performed and for any retention period required by Czech law (as set out in Express Rent's privacy notice)
- Transfer: the Czech Republic is an EU member state, so the EU GDPR applies in the same way.
- Legal basis: your consent (Art. 6(1)(a) EU GDPR) and the conclusion and performance of a contract (Art. 6(1)(b))
- Refusing consent: you may refuse, but then we cannot process a Prague quote or booking.
You conclude the rental contract directly with Express Rent at pick-up. Any data Express Rent processes from then on (for example ID documents and payment details) is covered by Express Rent's own privacy notice.
4-2. Processors and Transfers outside the EU
To run our service, we entrust the processing of personal information to, or share it with, the companies and bodies below.
- Google (Firebase, Google Cloud, Google Workspace): database, file storage (including document photos), backups, server functions and server access logs, login, sending emails, booking management spreadsheets, text recognition (OCR) of fine notices, protection of the corporate inquiry form against automated submissions (reCAPTCHA), website fonts (Google Fonts), videos (YouTube) and, if you consent, ad measurement and statistics (Google Ads, Google Analytics) — the database, the daily whole-database backup and the server functions are in the EU; file storage (including document photos, return photos, fine notices, and pick-up signatures and handover PDFs) and the daily file backup are in the United States; data for the other services may be processed outside the EU
- Anthropic: AI processing (see 4-3: reading fine notices, reading maintenance receipts and translating maintenance notes, chat assistant answers) — outside the EU, including the United States
- Barion Payment Zrt.: online payments, storing card tokens, payment fraud prevention (see 3-1) — Hungary

- Kakao Corp.: Kakao login — South Korea
- NAVER Corp.: search-ad conversion tracking if you consent (see section 3) — South Korea

- traffic fine deadline notifications: license plate, case number and the driver's name (or the booking number if the driver is not known)
- error notifications: the error details (including where in our code it occurred), the type of error, the random number created when the page was opened, the page address (without the part after "?" or "#") and browser information
- Express Rent: Prague round-trip rentals (see 4-1) — Czech Republic
- Pick-up and return partners (such as MoParK at Budapest Airport): carrying out pick-up and return for the bookings we assign to them — customer name (in Latin and Korean letters), booking dates and car, payment collected on site, the pick-up signature and, when the handover email is sent, its recipient address — Hungary
- Map, place search and image providers: OpenFreeMap (through the Cloudflare CDN, trip planner maps), komoot (trip planner place search), flagcdn.com (flag images) and Wikimedia (logo on the login page) — your browser loads these directly when you open the page or search, so they receive your IP address (see section 3)
- Insurers, repair and towing companies: to the extent needed to handle accidents and breakdowns — Hungary and the country where it happened
- Police, road authorities and tax authorities: handling fines and tolls, and answering requests made under the law — the country concerned
- JOAJOTOUR CORP. (our Korean affiliate): collecting unpaid amounts under the Terms — South Korea
If you contact us on KakaoTalk or WhatsApp, your messages are also processed under the terms and privacy policy of that messenger's operator.
Transfers outside the EU rely on the following safeguards. Anthropic: the EU Standard Contractual Clauses (SCCs) in the Data Processing Addendum that forms part of Anthropic's Commercial Terms. Kakao, NAVER and JOAJOTOUR CORP.: the European Commission's adequacy decision for the Republic of Korea. Google: the safeguards in Google's data processing terms. You can request a copy of these safeguards at the email address in section 6. We do not sell personal information.
For Telegram, Didit and the map, place search and image providers, we are still confirming where the data is processed and, for any transfer outside the EU, which safeguard applies. We will add this to this section once confirmed.
4-3. Use of AI (Artificial Intelligence)
We use AI from Anthropic for the tasks below. Anthropic processes the data on our behalf and on our instructions as our processor and does not use it to train its models. Processing may take place outside the EU, including in the United States, under the EU Standard Contractual Clauses (SCCs) in the Data Processing Addendum that forms part of Anthropic's Commercial Terms. Anthropic deletes the content within 30 days; content found to violate its usage policy may be kept for up to 2 years, and the related classification scores for up to 7 years.
Reading traffic fine notices (staff task): when we handle a fine notice or a driver-identification request from the authorities, we send a copy of the notice (image or PDF) and its text-recognition (OCR) result to Anthropic to read items such as the amount and the deadline and to write an explanation for our staff. Notices may contain the license plate and the driver's name, address and driver's license number. Before we charge or notify a customer about a fine, our staff check the values read by the AI against the original notice, and we never charge a customer on the basis of the AI result alone. We previously used Google Cloud's AI (Gemini) for this task.
- Legal basis (fine notices): performance of the rental contract (Art. 17 of the Terms; Art. 6(1)(b) EU GDPR), our legal obligation to answer driver-identification requests from the authorities (Art. 6(1)(c)), and our legitimate interest in handling fines accurately and quickly (Art. 6(1)(f))
Reading car maintenance receipts and translating maintenance notes (staff task): we send garage receipts (photos or PDFs) to Anthropic to read items such as the date, mileage and amount, and when we prepare a maintenance history report for selling a car, we also have it translate the maintenance notes written by our staff. Receipts may contain the license plate and the name of the person who brought the car in.
- Legal basis (maintenance receipts): our legitimate interest in keeping maintenance records for our cars and selling them (Art. 6(1)(f) EU GDPR)
Chat assistant (the AI assistant in the chat window on our website): questions you type into the chat window on our website are answered automatically by AI. Every answer written by AI is labelled “AI answer”. Answers to the common-question buttons are written by us in advance, so tapping a button alone sends nothing to the AI.
- What we send: your question, the earlier questions and answers in the same conversation (up to 6 messages in total, including questions and answers you opened with the common-question buttons), the path of the page you are on (without the part after "?" or "#") and the screen language. To help the AI answer, we also send our own guide material and price information, which contain no information about you. Anything that looks like a card number, email address, phone number, bank account number in IBAN format, Korean resident registration number, Korean driver's license number or passport number is masked automatically before it is sent to the AI. Automatic masking cannot recognize every format, and names and booking numbers are not masked. We do not send your IP address, visitor number or account details to Anthropic.
- Please do not type: what you type is kept in our records unmasked, exactly as written (see "Retention" below). Please do not enter names, booking numbers, card, passport or license details, health information or anyone else's information. For checking, changing or refunding a booking, we will direct you to our WhatsApp or KakaoTalk chat.
- Purposes and legal basis: answering your questions about renting a car (steps taken at your request before entering into a contract, Art. 6(1)(b) EU GDPR); running and improving the service, checking what we told you and preventing abuse (all based on our legitimate interests, Art. 6(1)(f))
- Transfer outside the EU: each time you send a question, it is passed from our servers (in the EU) over an encrypted connection to Anthropic (outside the EU, including the United States). Anthropic's role, the fact that it does not use the data to train its models, the transfer safeguard and how long Anthropic keeps the data are as described in the first paragraph of this section. If you do not want your question sent to the AI, please use the common-question buttons or contact us on WhatsApp or KakaoTalk. Conversation records are also included in our daily file backup in the United States (see "Retention" below).
- Retention: as a rule we keep every question you type in the chat window, including questions the chat assistant could not process because of usage limits, the length of the question, AI answers being switched off or an error, up to about 2,000 characters per question (for a longer question, only the first part is kept), together with the answers shown to you, in our database (in the EU) as the original, unmasked text; masking is applied only to what is sent to the AI. However, if an unusually large number of requests arrives in a short time, some of the questions that could not be processed are only counted and their text is not kept, and questions that never reach our servers (for example because the connection dropped) are not kept. These records are also included in our daily file backup, which is stored in the United States (see sections 4 and 4-2). With them we keep the time of the question, the screen language, the type of page you were on (a group such as "booking page" rather than the exact address), a random conversation number that groups the questions in one conversation, the topic category assigned by the AI, the links we showed, the outcome (answered, usage limit, error and so on) and processing details such as the response time. Opening the chat window, starting a new conversation, sending a question (without its text), the buttons you tap in the chat window, the links and contact buttons (KakaoTalk, WhatsApp) you use, your ratings of AI answers and the guidance cards shown to you are each recorded, together with the time, the screen language and the type of page, for each conversation under the same random conversation number, without any text or personal information. We use these records to check the quality of answers, to confirm what we told you (for inquiries and disputes) and to improve our guide material. They have no set deletion date, and we delete them if you ask us to (deleted records may remain in backups for up to 98 days, as described in section 4). Only our administrators can view them. We do not attach your IP address, visitor number or account details to them and do not link them to your visit records or bookings (anything you type yourself, such as a name or booking number, stays in the original text). To find your conversation, we therefore need you to tell us its date and content. The records used to limit how often the chat can be used (a value derived from your IP address with a secret key we hold, rather than the address itself, the times of use and any restriction status) are deleted from our database within 3 days of your last use (for backups, see section 4).
- Usage limits: if too many questions come from the same connection (IP address), or the AI repeatedly classifies questions from it as unrelated to car rental or inappropriate within a short time, we may block typed questions for a while. The common-question buttons and the contact buttons still work during that time.
- Nature of AI answers: AI answers can be wrong. Please always check prices and rental conditions on the booking screen, in your booking confirmation email, in our Terms and in the rental contract.
5. Rights of Data Subjects (EU GDPR Compliance)
You may request access, correction, deletion (right to be forgotten), or processing restriction of your personal information at any time. Please send your request to the contact below for prompt action.
You may also ask to receive the information you have given us in a machine-readable format or to have it transferred elsewhere (right to data portability). Where processing is based on your consent, you can withdraw it at any time, and you can object to processing based on our legitimate interests (such as our own statistics, server access logs, abuse prevention and the chat assistant). We reply to requests within one month and, if we need more time, we will tell you why. If you are unhappy with how we handle your personal information, you can lodge a complaint with the Hungarian supervisory authority (NAIH, Nemzeti Adatvédelmi és Információszabadság Hatóság, www.naih.hu).

This policy was drafted in compliance with EU GDPR. (Effective: August 2026)
Last amended: 16 October 2026. Section 4-3: updated how AI answers are marked in the chat window to match the current screen (every answer written by AI is labelled “AI answer”). Previous amendment (15 October 2026): sections 1, 3, 4 and 4-3: as a rule we now keep every question you type in the chat window, including questions the chat assistant could not process, up to about 2,000 characters per question, and record opening the chat window, the buttons, links and contact buttons you use in it and the guidance cards shown to you, with the time, for each conversation under a random conversation number. Earlier amendment (14 October 2026): sections 1 and 3: our own statistics now use the visitor number and the link to your booking number, and bookings now store ad click IDs, only after you accept in the cookie banner; added use of the chat window on our website and storage of its conversation (in this browser tab only). Added the chat assistant (AI answers in the chat window on our website) to section 4-3, with related changes to sections 1, 2, 3, 4, 4-2 and 5. Earlier amendment (11 October 2026): added identity verification (Didit), our own statistics, login, corporate inquiries, traffic fine handling, abuse prevention, server access logs and error reports to section 1 and the related purposes to section 2; our own statistics, reCAPTCHA and external fonts, images and videos to section 3; the hashed data sent to Barion to section 3-1; retention periods and backups to section 4; new sections 4-2 (processors and transfers outside the EU) and 4-3 (use of AI); and the rights to data portability and to object, our reply deadline and how to complain to the supervisory authority to section 5. Renamed section 6.
