Mentto Privacy Policy

Summary

Mentto works on your device. There is no Mentto account, no sign-up, no advertising, and no analytics or crash-reporting SDK. The records you keep are never sent to NexusDigitalLabs. If you turn on the optional Google Drive backup, a copy is saved to a hidden folder in your own Google Drive. If you buy Mentto Pro, Google Play or the App Store handles the payment and our billing provider, RevenueCat, confirms the purchase; none of them receives your students' details.

Information Stored on Your Device

To work, Mentto stores the following on your device only: your name (if you enter it) and currency; the students you add, with any phone number, email address, parent or guardian details and notes you choose to record; your groups; lesson times, one-off lessons, cancellations and moves; attendance; fee plans and the payments you record; your reminder settings; and any message templates you write. This information stays on your device. We do not run a server that receives it and we cannot see it.

Information About Your Students

Mentto is used by tutors to record information about the people they teach, some of whom may be children. As the tutor, you decide what to record and you are responsible for having your students' (or their parents') permission to keep it. Mentto only uses this information to show it to you, remind you of lessons and fees, and include it in backups, exports or messages that you choose to make.

When you send a reminder or receipt, or share a PDF or spreadsheet, Mentto hands the text or file to the app you pick (for example WhatsApp, SMS or email). From then on it is handled by that app and its provider under their own terms.

Notifications

Mentto can remind you before each lesson and on the day a fee falls due. These reminders are scheduled locally on your device. Mentto does not use remote push notifications and does not collect a push or device token. On iPhone and on Android 13 and later you are asked for permission first, and you can turn notifications off at any time. On Android, Mentto may also ask you to allow “Alarms & reminders” so reminders arrive on time; this only affects timing.

Optional Google Drive Backup

If you turn on automatic backup in Settings (a Mentto Pro feature), or restore a backup (always free), Mentto asks you to sign in with your Google account and to allow access to the app's own hidden application-data folder in your Drive. Mentto uses this to save copies of your records and to restore them on a new phone. Mentto can only see that one folder: it cannot see, read, or change any of your other Drive files. Backups go directly between your device and Google; they are not sent to NexusDigitalLabs. Mentto shows the email address of the connected Google account in the app so you can see which account is in use, and does not send it anywhere else.

You can turn backup off at any time in Settings, and you can delete the backups from your Google account (Google Drive → Settings → Manage apps → Mentto). Mentto's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.

Mentto Pro Purchases

Mentto Pro is sold through Google Play on Android and the App Store on iPhone. Google or Apple processes the payment; we never see your card or payment details. To confirm and restore purchases, Mentto uses RevenueCat, a billing service provider. RevenueCat receives a random identifier for your installation, your purchase and subscription status, and basic technical details such as the app version, operating system and store country. It does not receive your name, your students' details or any of your records. RevenueCat processes this on our behalf under its privacy policy. You can manage or cancel a subscription in Google Play or your Apple Account settings at any time; if Pro ends, nothing in the app is locked or deleted. Automatic backups pause, and backups already in your Drive stay there and can still be restored.

Files You Export

Mentto can create PDF receipts and statements and spreadsheet (CSV) exports of your students, payments and attendance. These are created on your device and only go where you choose to share or save them.

Device Backups

Android may include Mentto's data in your device backup to your Google account, and iPhone may include it in your iCloud Backup, depending on your device settings. These backups are handled by Google and Apple under their own terms, not by Mentto.

Advertising and Analytics

Mentto contains no advertising, no third-party analytics, and no tracking.

Store Diagnostics

If you have opted in on your device, Google Play may collect crash and performance diagnostics (Android vitals) about apps you use, including Mentto. This is collected by Google under its own policies and is available to us only in aggregate through the Play Console. On iPhone, if you have chosen to share analytics with app developers, Apple may provide us with similar crash and usage data under its own policies, in App Store Connect.

Data Retention & Deletion

Because your records live on your device, you control them. You can delete any student, payment or lesson in the app. Uninstalling Mentto, or on Android clearing its storage in your device settings, removes everything from the device. If you used Google Drive backup, you can also remove the backups from your Google account as described above. We hold no copy of your records, so there is nothing for us to delete on our side. Purchase records are kept by Google Play, Apple and RevenueCat as required for billing and tax.

Your Rights

Depending on where you live (including under GDPR and CCPA), you may have rights to access, correct, delete, or restrict personal data. Since we do not hold your Mentto records, these are exercised directly in the app, on your device and in your Google account. You can still contact us with any question or request.

Children's Privacy

Mentto is made for adults who teach, and is not directed at children. We do not knowingly collect personal information from children. Information a tutor records about a student stays on the tutor's device and in their own backups, as described above.

Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated date.
