Tacho Engine Hours & Service

Tacho Engine Hours & Service Privacy Policy

Last updated: October 2026

Summary

All your machines, logs and service records stay on your device. Tacho has no account. Subscriptions are handled by RevenueCat.

This policy covers the Tacho Engine Hours & Service app for iPhone and iPad, published by mk0.net, an independent app studio. It is written from what the app actually does in its code. Questions: [email protected].

What we receive

Nothing. We have no accounts or servers for this app.

What stays on your device

  • Your machines, serial and hull numbers, readings, fuel entries, maintenance items, service records, documents, checklists and notes are stored on this device.
  • Photos you add to a service are copied into the app's own storage on this device. The app only sees the photos you pick; it has no access to the rest of your library.
  • The widget shares service status with the app on the same device.

We cannot see this data. It is not uploaded to us.

Permissions the app may ask for

  • Notifications: Optional. Used to remind you when service is due or a document expires, scheduled on your device.
  • Camera: Optional. Asked only when you tap Take photo on a service record, to photograph a receipt or a part. Photos stay on this device.
  • Photos: No permission is requested. The system photo picker hands over only the pictures you choose.

Every permission is optional and can be changed later in the iPhone Settings app. Features that need a permission you decline simply stay unavailable.

Data that leaves your device

The app talks to the following services. Each receives only what is listed, and only for the purpose shown.

  • RevenueCat (subscription management): Used to handle your subscription: an anonymous user ID, purchase and subscription status, and basic device and app information. Their privacy policy.

Purchases

Subscriptions are sold and billed by Apple through the App Store. We never see your name, Apple ID, card or payment details. The app checks your subscription status through RevenueCat, which receives an anonymous ID and your purchase status, not your identity.

Ads, tracking and analytics

No ads, no tracking across apps or websites, and no data is sold. The app contains no analytics SDK.

Account

No account needed.

Children

Tacho Engine Hours & Service is not directed at children under 13, and we do not knowingly collect personal information from children.

Keeping and deleting your data

Settings > Delete all data removes everything the app stored on this device. Pro adds backup to a file, restore and CSV export. Deleting the app also removes all of its data from this device.

Your rights

Depending on where you live (for example under the GDPR, UK GDPR, CCPA or KVKK), you have the right to access, correct, export or delete your personal data. Because the app keeps your records on your own device, you can do most of this directly in the app or by deleting it. For anything else, or for data held by a service listed above, email [email protected] and we will help within 30 days.

Changes to this policy

If the app starts handling data differently, we will update this page and the date below before the change ships.
