By using Crankcase you agree to these terms and to Apple's Licensed Application End User License Agreement, which applies to every App Store app.
Crankcase helps you catalog vehicles you own, and lets you share a garage with other people or join one they share. It is provided as is. We work hard to keep it reliable, but we do not guarantee it will be error-free or always available.
You own your data. Keep your own backups by exporting from Settings → Data. We are not responsible for data loss caused by device failure, iCloud issues, or deletion.
Decoded specifications and recall notices come from public NHTSA data, whether the app or an assistant you connect asked for them, and may be incomplete or outdated. Recalls are matched by make, model, and year and may not apply to your specific vehicle. Always confirm safety information with the manufacturer or at nhtsa.gov. Values you enter or that an assistant sets are estimates, not appraisals.
You can share a garage with other people through iCloud. You are responsible for what you share and with whom: share only data you have the right to share, and invite only people you trust with it. People you invite are bound by these terms too, from the moment they use Crankcase. Crankcase stores none of the shared data on any server of ours; it travels through Apple's iCloud sharing from your iCloud to theirs. People you share with can use their own AI assistant on what you share with them, within the permissions you set. If someone shares a garage with you, its contents belong to them: they can change what is shared or stop sharing at any time, after which the garage leaves your devices, and changes you made in the moments before may not be kept. Changes you or your assistant make in a garage shared with you are your responsibility, are limited to what its owner allows, and are shown to everyone in the share with your name. Do not keep or pass on what others share with you beyond what they would expect.
Connecting an AI assistant is optional. It works only after you allow it in Settings → AI Assistant, where Crankcase lists what the assistant can read and which company receives it; our Privacy Policy describes the same in full. Anything an assistant reads or changes happens on your instruction to that assistant. The assistant's maker handles what it receives under its own terms and privacy policy, which you accept with your account with them; our connector handles it as our Privacy Policy says. Edits an assistant makes are applied by the app to your collection, and to garages shared with you within the permissions their owners set; you can turn on review so each edit to your own collection waits for your approval, undo applied edits, and turn off AI assistant access at any time, which signs out every assistant. Check what an assistant enters, especially values and safety information.
Tips are voluntary, one-time purchases through Apple. They unlock nothing and are not refundable by us; Apple handles refunds under its policies.
Do not use Crankcase to store data you do not have the right to store, to share data you do not have the right to share, or to interfere with the service or other users.
To the fullest extent permitted by law, Preston Siegel is not liable for indirect, incidental, or consequential damages arising from use of Crankcase. Total liability is limited to the amount you paid for the app, which is zero, plus any tips in the last 12 months.
We may update these terms; the date above changes when we do. Continued use means acceptance.
