Privacy Policy

Last updated: July 22, 2026

CarNote ("the App", "we") helps you log your car's fuel, washes, and maintenance. This policy explains what information the App handles, how it is stored, and your choices.

1. Using the App Without an Account (Guest Mode)

You can use the App in guest mode without signing in. In guest mode, no account is created and none of your data is sent to our servers — all records stay on your device only. Sync and backup are not available in guest mode.

2. Information We Collect When You Sign In

If you sign in with Google or Apple to enable sync and backup, we collect and store the following on our servers, linked to your account:

Account information

• Your email address and display name provided by Google or Apple, and a provider account identifier. These are used to identify your account and sync your data across devices.

Content you create

• Vehicle records: type (fuel / wash / maintenance), date, odometer reading, cost, fuel amount, and any notes you add.
• Vehicles: name, brand, and model.
• Places: a place name and its coordinates (latitude / longitude), captured from your device's location at the moment you save a place. Places are used to label records and to suggest nearby places later.

3. Location

The App uses location in two distinct ways:

• While using the App: to capture the coordinates of a place you choose to save and to suggest nearby places. When you are signed in, these saved place coordinates are synced to your account (see Section 2).
• Automatic mileage tracking (optional, background): if you enable this feature, the App accumulates your driving distance in the background — only while you are actually driving, detected using your device's motion sensor to save battery. This background location is used solely on your device to calculate distance and is not transmitted to our servers.

You can grant, limit, or revoke location and motion permissions at any time in your device's Settings.

4. How We Use Information

We use your information only to operate the App's features: syncing and backing up your records across devices, showing spending and fuel-economy charts, and delivering maintenance reminders. We do not use your information for advertising or marketing.

5. Third Parties

We use Google Sign-In and Sign in with Apple for authentication only. The App contains no advertising SDKs and no analytics or tracking SDKs, and we do not sell or share your information with third parties for their own purposes.

6. Data Storage & Security

When you are signed in, your data is stored on our servers and transmitted over encrypted connections (HTTPS). Guest-mode data is stored only in a local database on your device.

7. Data Retention & Deletion

You can delete individual records, vehicles, and places within the App at any time. If you are signed in, you can permanently delete your account from Settings → Delete account; this removes your account and all associated data (email, records, vehicles, and places) from our servers. In guest mode, deleting the App removes all of its data from your device.

8. Children's Privacy

The App is not directed to children and does not knowingly collect information from children.

9. Changes to This Policy

If this policy changes, we will update this page and revise the "Last updated" date above.
