Privacy Policy - Nettora

Last updated: 12 August 2026

Nettora (“the app”) is a compound interest calculator published by AppVita Studio. This page explains what data the app handles and what our advertising partner collects.

Summary

• Nettora has no account and no registration.
• Your calculations, saved scenarios and settings stay on your device.
• We do not operate any server and we do not receive your financial figures.
• The app shows advertising provided by Google AdMob, which does collect some data.
• The app contains no in-app purchases.

Data the app stores on your device

Nettora saves the following in the local storage of your device, and nowhere else:

• the values you enter (initial capital, contributions, rate, duration, tax rate, inflation)
• scenarios you choose to save, and any note you attach to them
• your preferences: language, currency, theme, accent colour, sound, number format

This information never leaves your device unless you deliberately export it (PDF, CSV or backup file) and choose where to send it. Uninstalling the app deletes it. You can also erase it at any time from inside the app.

Advertising (Google AdMob)

Nettora is free and is funded by advertising served by Google AdMob (Google Ireland Limited / Google LLC).

To show ads, Google may collect and process:

• the advertising ID of your device and other device identifiers
• technical device data (model, operating system version, language)
• approximate location, derived from your IP address
• interaction with the ads that are shown

Google acts as an independent data controller for this processing. Its policy is available at https://policies.google.com/technologies/ads.

Consent (GDPR)

If you are in the European Economic Area, the United Kingdom or Switzerland, the first time you open the app you are shown a consent message provided by Google (UMP SDK). No ad is requested before you make your choice.

You can change or withdraw your consent at any time: open the app, go to Settings > Ad privacy settings. The same message will be shown again and your new choice takes effect immediately.

If you do not consent to personalised ads, the app keeps working exactly the same and shows non-personalised ads instead.

Optional reward video

The app offers an optional video ad that removes banners for 24 hours. Watching it is entirely your choice: nothing in the app is locked behind it.

Data we do NOT collect

• no name, e-mail address or telephone number
• no account, no login, no user profile
• no analytics of your behaviour inside the app
• no transmission of your financial data to us or to third parties
• no precise (GPS) location
• no access to contacts, photos, microphone or camera

Children

Nettora is a general-purpose financial calculator and is not directed to children under 13. We do not knowingly collect data from children.

Permissions used

• Internet: required only to load advertising.
• Advertising ID (com.google.android.gms.permission.AD_ID): required by Google AdMob to serve ads and to respect your consent choice.

Your rights

Because we hold no personal data about you, there is nothing for us to export or delete on our side: you are already in full control of everything the app stores, directly on your device. For data collected by Google as advertising provider, you may exercise your rights through Google using the link above, and through the in-app consent message.

Not financial advice

Nettora is a calculation tool. Its results are estimates based on the assumptions you enter and do not constitute financial advice, an offer or a recommendation.

Changes to this policy

Any future change will be published on this page with a new “Last updated” date.
