Privacy Policy

Last updated: October 3, 2026

1. Introduction

GarageLog (the “Service”) respects your privacy and takes the utmost care to protect your personal information. This Privacy Policy explains how the Service collects, uses, and protects your personal information.

2. Information We Collect

2.1 Account information

  • Email address (when registering with an email address and password)
  • Google account information (email address, name, profile image)
  • Apple Account information (email address, or a relay address when you use Apple's Hide My Email)
  • User ID (Firebase Authentication)

2.2 Vehicle and maintenance information

  • Vehicle information (name, model code, year, first registration month, mileage, inspection expiry date, body color, etc.)
  • Registration (license plate) number and chassis number (only if you enter them yourself)
  • Maintenance records (date, details, cost, where the work was done, images, etc.)
  • Fuel and charging records (date, quantity, cost, station name, etc.)
  • Modification history
  • Inspection and maintenance record sheets (inspection results, the name of the person or business that performed the work, and their address; the address is optional)

2.3 Location information

When you log a fill-up in the iPhone app, we use your current location to suggest nearby station names. We do not store your current location itself. If you pick one of the suggested stations, we save that station's location (latitude, longitude, and city name) with the fuel record. If you do not allow location access, no location is collected. We do not track your movements. The web version does not collect location information.

2.4 Information contained in photos and images

Photos you upload may show names and addresses printed on documents, license plates, and similar details.

For vehicle photos, photos for public pages, and images attached to maintenance or modification records, we remove embedded metadata such as the place the photo was taken when you upload them. Images attached to maintenance or modification records on the web version before the October 2026 change may still contain that metadata.

On the web version, the original of an image saved as evidence is stored as the original file, in a location only you can access. Public pages show only images that have gone through the masking step.

2.5 Usage information

  • Access logs (IP address, browser information)
  • Usage data (feature usage frequency; collected via Google Analytics / Firebase Analytics)
  • Error and crash information (collected via Sentry; on the web version, your user ID and email address are sent along with it so we can investigate the cause)
  • Reports submitted on public pages (reason and details; can be sent without signing in)

2.6 Pre-release and waitlist information

  • Email address
  • Vehicle model and interest details you optionally provide

3. How We Use Information

  • Providing and operating the Service
  • User support
  • Improving the Service and developing new features
  • Sending pre-release notices and updates about new features such as the iOS app
  • Maintaining security and preventing misuse
  • Statistical analysis (using usage data that does not include your name or email address)
  • Compliance with applicable laws

4. Sharing of Information

The Service does not provide your personal information to third parties except in the following cases:

  • When you have given consent
  • When you publish information yourself using the sharing features (share URLs, the “Community Garage,” etc.). Published vehicle information, records, and photos can be viewed by anyone, and you can stop sharing at any time.
  • When required by law
  • Provision to service providers as necessary to operate the Service (Firebase, Sentry, etc.)

Public pages show the vehicle name, model code, year, and mileage, the maintenance and modification records you chose to publish, and the photos you published (sale pages also show the inspection expiry date). They do not show your email address, name, address, registration number, chassis number, or the location saved with fuel records. Anything you write in a record's text or notes, and anything visible in your photos, is shown as is.

5. Data Storage

User data is stored on Firebase (Cloud Firestore, Cloud Storage) operated by Google. Data is encrypted and managed under appropriate security measures.

6. Cookies and Tracking

The Service uses cookies for the following purposes:

  • Maintaining your login state
  • Saving your settings
  • Access analytics (Google Analytics / Firebase Analytics; aggregated against a per-device or per-app identifier, and your name and email address are not sent)
  • Measuring clicks on affiliate links (see section 7 below)

You can disable cookies in your browser settings, but some features may be limited.

7. Affiliate Links

The Service may introduce third-party services such as vehicle inspection, auto insurance, and car buying services. These introductions may contain advertising (affiliate) links, and the Service may receive a referral fee when you sign up through them. Advertising links are labeled as such.

When you follow an advertising link, the Service records only aggregate click counts per offer. We do not send any personally identifiable information (such as your name, email address, or vehicle details) to the destination provider.

Handling of personal information on the destination site is governed by that provider's own privacy policy. The Service is not responsible for the content of third-party services.

8. Your Rights

You have the following rights regarding your personal information:

  • Right of access: the right to review your data
  • Right to rectification: the right to correct inaccurate data
  • Right to erasure: the right to request deletion of your data
  • Right to export: the right to download your data

To exercise these rights, please contact us through the support page.

9. Data Deletion

When you delete your account, your personal information and all data are permanently deleted. However, data that is required to be retained by law, or anonymized statistical data, may be kept.

10. Children's Privacy

The Service does not knowingly collect personal information from children under 13 years of age.

11. Changes to This Policy

The Service may revise this Privacy Policy as necessary. If there are material changes, we will notify you within the Service.
