Tappet helps you understand and look after your car. It is not a mechanic, and nothing it tells you is a substitute for someone qualified looking at the actual vehicle.
Last updated 13 September 2026
These terms cover your use of the Tappet app and website, operated by Southmoor Digital LLC. Using Tappet means you accept them.
Tappet™ is a trademark of Southmoor Digital LLC.
Tappet produces estimates, ranges and comparisons from the information you give it and from public data about your vehicle. It has never seen your car.
It is not a safety inspection, a diagnosis, or professional advice. A health score, a maintenance estimate or an answer from the advisor is a starting point for a conversation with a qualified mechanic — never a replacement for one, and never a reason to delay having something looked at. If you have any reason to think your vehicle is unsafe, stop driving it and have it inspected.
Recall information comes from NHTSA and may lag. We show what their public database returns. An absence of recalls here is not a guarantee that none exists, and the manufacturer’s own notice is authoritative.
Modification guidance is not a legality check.Emissions rules, inspection requirements and insurance consequences vary by where you live, and Tappet does not check any of them. Modifying a vehicle may void warranties and may be illegal on public roads where you are.
Keep your password to yourself; you are responsible for what happens under your account. Tell us if you think someone else has access to it. You can delete your account at any time from inside the app or the website.
Your photographs, invoices and notes stay yours. You give us permission to store and process them for the sole purpose of operating Tappet for you — including sending the relevant details to the AI provider described in the Privacy Policy in order to answer your questions. We do not use your content to train models, and we do not publish it.
Only upload things you have the right to upload.
Do not attempt to break, overload or reverse-engineer the service, use it to build a competing product, or use it for anything unlawful. AI features carry per-account limits so that one account cannot exhaust the service for everyone; those limits may change.
Paid subscriptions are sold and billed through the App Store. Payment is taken by Apple when you confirm the purchase, and the subscription renews automatically for the same period unless you turn renewal off at least 24 hours before it ends.
You cancel through Apple, not through us — in Settings → your name → Subscriptions. We cannot cancel it on your behalf, and deleting your Tappet account does not stop the billing. Cancel first, or you will keep being charged after the account is gone. Refunds are handled by Apple under their terms.
Tappet is provided as it is. We do not promise it will always be available, that its answers will always be right, or that it will never lose data — though we try hard at all three. To the fullest extent the law allows, we are not liable for indirect or consequential loss arising from your use of it, and nothing in these terms limits liability that cannot legally be limited.
You can stop using Tappet and delete your account whenever you like. We may suspend or close an account that breaks these terms.
If these terms change in substance, the date at the top changes with them.
