PRIVACY POLICY – VEHICLE DIARY
Last updated: October 14, 2026
Vehicle Diary ("the app", "we") is a service logbook for motorbikes and cars. This policy explains what the app stores, what it sends, who receives it, and how you delete it.
1. SUMMARY
- You can use the app without an account. In that case all of your data stays on your device.
- Only when you sign in is your data backed up to our server, so you can use it on several devices and restore it on a new one.
- The app shows no ads, uses no behavioural analytics, and never sells or trades your data.
- Text on receipt photos and odometer photos is read on your device; photos are not sent anywhere for recognition.
2. DATA STORED ON YOUR DEVICE
What you enter is stored in the app's private storage:
- Vehicle details: type, brand, model, model year, plate number, nickname, vehicle photos.
- Odometer readings and their history.
- Service, repair, fuel and expense records, notes, workshop names, and receipt photos you attach.
- Vehicle documents and expiry dates (inspection, emission test, insurance, registration...), document photos you attach, and the province you select.
- Settings: language, theme, units, currency, reminder time, widget options.
If you add the home screen widget, a small summary (vehicle name, plate, odometer, a few upcoming items) is stored in a data area shared between the app and the widget. It stays on your device.
Uninstalling the app deletes all data on the device. If you were not signed in and had not backed up, that data cannot be recovered.
3. CAMERA AND PHOTO LIBRARY
The app only uses the camera or photo library when you tap to take or pick a photo, in order to:
- Take photos of your vehicle, receipts and documents and save them to your logbook.
- Read receipt text to fill in expenses, and read the number on your odometer.
Text recognition runs entirely on your device using the operating system's built-in technology (Apple Vision on iPhone, Google ML Kit on Android). Photos are not uploaded for recognition. Odometer photos are deleted right after the number is read; receipt photos are kept only if you save them to your logbook.
On Android, to read Japanese, Chinese or Korean receipts, your device may download a text recognition model from Google Play Services the first time. This download does not send your photos.
4. ACCOUNT AND BACKUP (OPTIONAL)
You can create an account with email and password, or sign in with Google or Apple.
With Sign in with Apple we receive a token issued by Apple, and the name and email you choose to share. If you choose "Hide My Email", we receive an Apple relay address instead of your real email.
When you have an account, our server (xe.dolong.online) receives and stores:
- Account details: email, name (if you enter it or your Google account provides it), and a hashed password (for email accounts). With Google sign-in we receive a token issued by Google to verify your account; we never receive your Google password.
- A copy of the logbook data in section 2 (except on-device settings), including attached photos, to sync between devices and restore when needed.
- The Pro status of your account.
We email you only to verify your address and to reset your password (one-time code).
Like any web service, the server logs IP addresses and access times for operation and abuse prevention.
5. PRO PURCHASES
Payments are processed by Apple (App Store) or Google (Google Play). We never receive or store your card or payment details.
To unlock Pro, the app sends the purchase information issued by the store (product ID, transaction ID, receipt or purchase token, platform) to our server, which verifies it with Apple or Google and records Pro on your account.
6. THIRD-PARTY SERVICES
- Apple App Store / Google Play: app distribution and payment processing, under Apple's and Google's own policies.
- Google Sign-In: when you choose to sign in with Google, under Google's Privacy Policy.
- Firebase Remote Config (Google): lets us change some settings remotely, such as announcing a new version. Google receives a random app installation ID; no logbook data is sent through it.
- YouTube (Google): when you open a video guide in the app, the video is played from YouTube. YouTube may receive your IP address and device information and set cookies, under the YouTube Terms of Service and Google's Privacy Policy.
- Google Play Services (Android): provides the text recognition models described in section 3.
- Sign in with Apple: when you choose to sign in with Apple, under Apple's Privacy Policy.
- Gmail (Google): delivers our verification and password-reset emails. Google processes the recipient address and message content to deliver them.
7. NOTIFICATIONS
Service and document expiry reminders are scheduled on your device. They do not go through our server. You can turn notifications off at any time in the app or in your phone's settings.
8. WHAT WE DO NOT DO
- We do not collect your location, contacts, microphone or health data.
- We show no ads and use no advertising identifiers.
- We use no behavioural analytics tools.
- We do not sell, rent or trade your data.
- In-app issue reports do not go through our server: the app opens your own email app with a pre-filled message (including device and app version information). You review it and decide whether to send it.
9. SHARING
We only share data when:
- You choose to share it, for example by exporting your service history as a PDF and sending it to someone.
- The law requires it, under a valid order from a competent authority.
10. SECURITY
Data between the app and our server travels over encrypted connections (HTTPS). Passwords are stored as one-way hashes. No system is perfectly secure, so please use a strong password that you do not reuse elsewhere.
11. DELETING YOUR DATA
- Delete data on your device: Profile → Settings → Backup → Erase all data, or uninstall the app.
- Delete your account: Profile → Account → Delete account (when signed in). This deletes your account, all synced data and the photos you uploaded to our server, and also erases the data on the current device. It cannot be undone.
- If you cannot do this in the app, email us from your account's email address and we will handle it within 30 days.
We keep your account and synced data for as long as your account exists. When you delete your account, it is removed from our server immediately, along with your photos. Server access logs are kept for up to 90 days.
Deleting your account does not cancel a Pro subscription. Cancel it in your App Store or Google Play subscription settings.
12. CHILDREN
The app is not intended for children under 13, and we do not knowingly collect children's data. If you believe a child has created an account, contact us and we will delete it.
13. CHANGES
When this policy changes, the "Last updated" date above will change. Significant changes will be announced in the app.
TERMS OF SERVICE
By downloading, installing or using the Vehicle Diary app ("the app"), you agree to these terms. If you do not agree, please do not use the app.
1. WHAT THE APP DOES
Vehicle Diary helps you record and track maintenance for motorbikes and cars: reminders for routine items by distance and time, service, repair, fuel and expense history, vehicle documents and expiry dates, plus tools such as receipt reading, odometer reading, a home screen widget and PDF export of your history.
2. INFORMATION IS FOR REFERENCE ONLY
- Service schedules, part replacement intervals and estimated mileage in the app are general suggestions based on the data you enter and common recommendations. They do not replace your manufacturer's manual or the advice of a mechanic, workshop or dealer. Follow your vehicle manufacturer's instructions.
- Information about inspections, emission tests, emission levels, provincial rollout schedules and other regulations is for reference only and may be outdated or not cover every case. Official legal documents and guidance from the competent authorities are the only authoritative source.
- Text read from receipts and numbers read from odometers may be wrong. Check them before saving.
- Reminders depend on your phone's notification settings and may not appear on time (for example when the phone is off, in battery saving mode, or notifications are disabled).
You are responsible for the condition of your vehicle, its maintenance and your compliance with vehicle regulations. We are not liable for vehicle damage, accidents, fines or costs arising from reliance on information in the app.
3. ACCOUNTS
- You can use the app without an account. An account is only needed for backup, syncing across devices and linking Pro.
- You are responsible for keeping your password secret and for all activity under your account.
- You can delete your account at any time in the app (Profile → Account → Delete account).
- We may suspend or delete accounts used for abuse, attacks on the service, or unlawful purposes.
4. YOUR DATA
The data you enter is yours. You allow us to store and process it only to provide the service (on-device storage, and backup and sync when you sign in), as described in the Privacy Policy.
We work to keep your data safe but do not guarantee that the backup service will never be interrupted or lose data. Back up regularly and keep PDF exports of important records.
5. PRO
- The free version supports up to 5 vehicles. Pro unlocks unlimited vehicles, detailed cost reports, fuel consumption charts and PDF export of your service history. The list of benefits shown in the app is the one currently in effect.
- Plans: monthly and yearly (auto-renewing subscriptions) and lifetime (one-time purchase). Prices shown in the app are provided by the App Store or Google Play for your country and include taxes as determined by the store.
- Payment is charged to your App Store or Google Play account when you confirm the purchase.
- Subscriptions renew automatically at the end of each period unless auto-renew is turned off at least 24 hours before the current period ends. You manage and cancel subscriptions in your App Store or Google Play account settings. After cancelling, Pro remains active until the end of the paid period.
- Pro is linked to your Vehicle Diary account; sign in with the same account on another device to use it. You can restore past purchases with the "Restore purchase" button in the app.
- Refunds are decided by Apple or Google under their policies. We do not issue refunds directly.
- Deleting the app or your account does not cancel a subscription.
6. ACCEPTABLE USE
You agree not to:
- Reverse engineer, tamper with, attack or overload the app or our servers.
- Use the app to store or distribute unlawful content or content that infringes others' rights.
- Bypass the payment system to use Pro without paying.
7. THIRD-PARTY CONTENT
The app may display or open content and services from third parties (YouTube, Google, Apple, external websites). Their use is governed by the providers' own terms. We are not responsible for third-party content.
8. INTELLECTUAL PROPERTY
The app, its interface, icons, images and the content we create belong to the developer of Vehicle Diary. Vehicle and part brand names and trademarks shown in the app belong to their respective owners and are used for identification only.
9. LIMITATION OF LIABILITY
The app is provided "as is". To the extent permitted by law, we do not guarantee that the app will be uninterrupted, error-free or fit for any particular purpose, and we are not liable for indirect damages arising from the use of or inability to use the app. Our total liability, if any, will not exceed the amount you paid for Pro in the last 12 months.
10. CHANGES AND TERMINATION
We may update the app, change features or discontinue the service. If we discontinue the backup service, we will give reasonable notice so you can save your data. These terms may be amended; the "Last updated" date will change, and continuing to use the app afterwards means you accept the new terms.
