Privacy Policy
Last updated November 9, 2026
Parts Bench (“we”, “us”) is a free vehicle parts, garage and maintenance app at mypartsbench.com. This policy explains what we collect, why, who helps us run the app, and the choices you have. We have tried to keep it in plain language.
The short version. You can use most of Parts Bench without an account. Without one, your garage stays on your own device. We do not sell your personal information, and we do not show ads. You can delete your account and its data yourself at any time in Settings.
1. What we collect
If you don’t have an account:
- Your garage (the vehicles you add, such as year, make, model, trim, VIN, mileage, nickname and maintenance logs) is saved in your browser’s storage on your device. We don’t receive it.
- When you decode a VIN, pick a year, make and model, or check recalls, the app sends that information to the U.S. National Highway Traffic Safety Administration (NHTSA) to get the results.
- When you search for parts, the app sends your vehicle’s year, make, model (and trim if you choose to include it) and the part you searched for to our server, which asks eBay for matching listings. We don’t build a profile or history of your searches.
If you create an account:
- Your email address and the account name you choose. We email you a one-time sign-in code each time you sign in. There are no passwords.
- Your garage, which is then saved to your account so it follows you to your other devices.
- Ideas you post on the Ideas board (title, details, type and your account name). These are public. Your votes are private; only the totals are shown.
- Messages you send through Contact support (the text, the topic, and your account email so we can reply). These are private.
Technical information. Like any website, our hosting and sign-in providers process standard request information such as your IP address, browser type and the pages requested, to deliver the site and keep it secure.
2. How we use it
- To run the app: identify your vehicle, show maintenance and parts, and keep your garage in sync.
- To sign you in and keep your account secure, including limits and bot checks that stop abuse.
- To answer your support messages and to understand what to build next from the ideas people share.
We do not use your information for advertising, and we do not sell it.
3. Who else handles your information
We use a small number of services to run Parts Bench. They only get what they need to do their job.
| Service | What it does |
|---|---|
| Supabase | Account sign-in and our database (email, account name, garage, ideas, votes, support messages). |
| Resend | Sends your sign-in code emails (your email address). |
| Vercel | Hosts the website and runs our server functions. |
| Cloudflare | Our domain name service. If we show a bot check when you sign in, it is Cloudflare Turnstile, which looks at signals from your browser to tell people from bots. |
| Google Fonts | Delivers the fonts we use. Google receives your IP address when the fonts load. |
| NHTSA | U.S. government vehicle database used for VIN decoding, makes and models, and recalls. |
| eBay and other stores | When you tap a link you leave Parts Bench. The store’s own privacy policy applies from then on. |
We may also share information if the law requires it, or to protect the safety and rights of our users and the service.
4. Affiliate links
Many links to eBay and other stores are affiliate links. If you buy after clicking one, we may earn a commission at no extra cost to you. To credit us, the store or its affiliate network (such as the eBay Partner Network) may set cookies or similar technology when you visit it. We don’t receive your name, payment details or what else you bought.
5. Cookies and device storage
Parts Bench uses your browser’s local storage and a service-worker cache for things the app needs to work: your garage, your sign-in session, a saved list of vehicle makes, and offline access. We don’t use advertising cookies and we don’t currently use analytics tools. Stores you click through to may set their own cookies.
6. Your choices and rights
- Delete your account. In Settings, choose Delete account. This permanently removes your account, your saved garage, and the ideas, votes and support messages you posted from our database. Copies may remain briefly in our providers’ routine backups until they expire.
- Sign out. Signing out clears the garage from that device. It stays in your account.
- See or fix your information. Your account name, email and garage can be edited in the app. For anything else, contact us (below).
- Device data. You can clear Parts Bench data from your browser settings at any time.
Depending on where you live (for example California and some other U.S. states), you may have the right to know what we hold about you, ask us to correct or delete it, and not be discriminated against for doing so. We don’t sell personal information or share it for cross-context advertising. To make a request, contact us below.
7. Security
Connections to Parts Bench are encrypted, and our database rules mean each person can only read their own garage and support messages. No online service can promise perfect security, so please use an email account that only you can access.
8. Children
Parts Bench is not meant for children under 13, and we don’t knowingly collect information from them. If you think a child has given us information, contact us and we will delete it.
9. Where your information is processed
Our providers may process information in the United States and other countries.
10. Changes
We may update this policy. When we do, we will change the date at the top, and for significant changes we will say so in the app.
