Car Log (Car Maintenance Log & Tracker) is made by Plainwork Apps. Last updated November 8, 2026.
Your vehicles, service records, fill-ups, parts, warranties and photos are stored on your phone. There is no account and no sign-in. We do not show ads and we do not use any advertising or tracking tools.
When you tap a Snap button (a part label, a shop bill, the odometer, a gas pump or a VIN), that photo is sent over an encrypted connection to our server so the numbers on it can be read. The server passes the photo to Anthropic, the company that provides the reading, and sends back what was read. Photos are not kept on our server after the reading. Anthropic handles them under its commercial terms and does not use them to train its models. To limit how many photos each phone can read, the server keeps a random number that identifies the phone and the time of each reading, with no photo and no record content.
When you check recalls, the year, make and model are sent to the U.S. government recall list (NHTSA). When a VIN is read, the VIN is sent to NHTSA's free vehicle decoder to fill in the year, make and model. Nothing else is sent.
If you turn on sharing, your records (not your photos) are locked with your private key on your phone before they are sent to our server, so the server cannot read them. Anyone with the key can see the shared records. You can stop sharing and erase the shared copy at any time in the app.
The full version is bought through Google Play. We never see your payment details.
Backup files, PDFs and spreadsheets are made on your phone and go only where you send them.
Delete a vehicle in the app, or uninstall the app, and the records and photos on your phone are removed. To erase a shared copy, use Stop sharing in the app. Questions: eshemp1000@gmail.com.
Car Log is not directed to children under 13.
