Privacy Policy
Effective date: 23 October 2026
This policy explains how Gaugo: Mileage & Fuel Tracker ("Gaugo", "we", "us") handles your information when you use the Gaugo Android app and this website. We keep it simple: we collect only what's needed to make Gaugo work, we never sell your data, and you can delete everything at any time.
1. Information we collect
Information you give us
- Account details. Your name. If you create an account, your email address, or your Google account's name and email if you sign in with Google. Passwords are handled by Firebase Authentication and are never visible to us.
- Preferences. Your country, currency, units (for example miles or kilometres) and notification setting.
- Vehicle information. The vehicles you add, such as nickname, type, make, model, year, number plate, fuel type, tank size, starting odometer and card colour.
- Records you log. Fill-ups (date, odometer, quantity, amount paid, station, notes), services (work done, cost, garage, notes), expenses (category, amount, notes) and reminders.
Information collected automatically
- Account identifier. A unique user ID created by Firebase Authentication. If you use Gaugo without an account, an anonymous ID is used instead.
- Technical data needed to run the service. When the app connects to our backend, our provider (Google Firebase) processes standard technical information, such as your IP address and basic device and app information, to authenticate you, keep the service secure and deliver your data.
What we don't collect
We do not collect your precise or approximate location, contacts, photos, files, health data, messages or the advertising ID. Gaugo contains no advertising SDKs and no analytics or tracking SDKs.
2. How we use your information
- To provide the app: storing your vehicles and records, calculating mileage, costs and statistics, and syncing them across your devices.
- To create and secure your account, and to let you sign in, sign out and delete your account.
- To schedule the reminder notifications you ask for. These are scheduled on your device.
- To respond when you contact us for support.
- To keep Gaugo safe and working, for example preventing abuse and fixing problems.
We do not use your information for advertising, and we do not make automated decisions that have legal or similarly significant effects on you.
3. Legal bases (EEA and UK users)
We process your information because it's necessary to provide the app you asked for (performance of a contract), for our legitimate interests in keeping Gaugo secure and working, and, where needed, with your consent (for example notifications, which you can turn off at any time).
4. Where your data is stored, and our service providers
Gaugo uses Google Firebase, provided by Google LLC, as its backend:
| Service | Purpose | Data |
|---|---|---|
| Firebase Authentication | Sign-in (email, Google or anonymous) | Name, email, user ID, sign-in metadata |
| Firebase Realtime Database | Storing and syncing your Gaugo data | Profile, preferences, vehicles and records |
| Firebase Hosting | Serving this website | Standard web server logs |
| Google Play services | App distribution and the optional in-app rating prompt | Handled by Google under its own policy |
Your data is stored on Google's servers, which may be located in the United States or other countries. Google processes this data on our behalf under its data processing terms, which include safeguards such as Standard Contractual Clauses for international transfers. You can read Firebase's privacy information and Google's Privacy Policy.
Your data is also cached on your device so the app works offline. Access rules ensure that each account can read and write only its own data.
5. How we share information
We do not sell, rent or trade your personal information, and we do not "share" it for cross-context behavioural advertising. We disclose information only:
- to service providers that help us run Gaugo (listed above), under contracts that limit their use of it;
- if required by law, or to protect the rights, safety and security of our users, the public or Gaugo;
- as part of a merger, acquisition or sale of assets, in which case we'll tell you before your information becomes subject to a different policy.
6. Retention and deletion
We keep your data for as long as your account exists. You can delete it at any time:
- Delete a record or vehicle in the app. Deleting a vehicle removes all its fill-ups, services, expenses and reminders.
- Delete your account in Settings → Delete account. This permanently deletes your account and all data stored with it. It works for guest (no-account) users too.
- Delete your account on the web by signing in on our Delete account page with the email and password, or Google account, you use in Gaugo.
- Or email us and we'll delete it for you.
Deleted data is removed from our live database right away. Residual copies in our provider's backups may persist for a limited period before being overwritten. If you uninstall the app while using it as a guest, without deleting your account first, contact us and we'll help delete that data.
7. Your rights and choices
Depending on where you live, including under the EU/UK GDPR, the California Consumer Privacy Act (CCPA/CPRA) and India's Digital Personal Data Protection Act, 2023, you may have the right to:
- access the personal data we hold about you and get a copy of it;
- correct inaccurate data (most of it you can edit directly in the app);
- delete your data and account;
- object to or restrict certain processing, and withdraw consent;
- data portability;
- nominate another person to exercise your rights (India);
- complain to your local data protection authority.
To exercise any of these rights, email us at the address below. We'll respond within the time required by law, usually 30 days, and won't discriminate against you for exercising them. You can turn reminder notifications off in Gaugo's settings or in your phone's settings at any time.
8. Security
Data is encrypted in transit (HTTPS/TLS) and stored by Google with encryption at rest. Database rules restrict every account to its own data. No method of transmission or storage is 100% secure, but we work to protect your information and will notify you and the authorities of a breach where the law requires it.
9. App permissions
- Internet: to sign in and sync your data.
- Notifications: to show the service and renewal reminders you set (Android 13+ asks your permission).
- Run at startup: to restore your scheduled reminders after the phone restarts.
- Vibration: for haptic feedback.
- Motion sensor (accelerometer): used only on your device to tilt the vehicle cards for a visual effect. Sensor readings are never stored or sent anywhere.
10. Children
Gaugo is intended for adults who own or drive vehicles and is not directed at children under 13 (or the minimum age in your country). We don't knowingly collect children's personal information. If you believe a child has given us information, contact us and we'll delete it.
11. This website
This website does not use cookies, analytics or advertising trackers, and its fonts and images are served from our own site. Our hosting provider (Firebase Hosting) may keep standard server logs, such as IP address, browser type and pages requested, for security and reliability.
The Delete account page is the only page that loads code from a third party: the Firebase JavaScript SDK, from Google's servers. When you sign in there, your email and password go directly to Firebase Authentication to verify you. We never see or store your password. The page keeps your sign-in in memory only, so it ends when you close the tab.
12. Changes to this policy
We may update this policy from time to time. We'll change the effective date above and, for significant changes, tell you in the app before they take effect.
