Privacy policy.

Short, because there is very little to say: we don't collect your data.

Last updated: 14 October 2026

Short version: ScreenBlock does not collect, store, or transmit any personal data. Everything it does happens on your device, and nothing on your screen ever leaves your phone. This website uses no cookies, analytics, or tracking.

1. Who we are

Truth Ocean is an independent app studio. This policy covers the ScreenBlock app for Android and the truthocean.app websites, including screenblock.truthocean.app.

2. The ScreenBlock app

ScreenBlock collects no data. It does not collect, store, transmit, or share:

  • Screenshots or anything shown on your screen
  • Personal information or contact details
  • Device identifiers or advertising IDs
  • Usage statistics, analytics, or crash reports
  • Location data

To detect explicit content, ScreenBlock passes screen frames to an AI model that runs on your phone. Each frame is analysed in memory and discarded straight away. Frames are never saved to storage and never sent anywhere. ScreenBlock has no servers and no accounts.

What stays on your phone

A few settings are saved on your device so the app works the way you set it up: your PIN, the detection sensitivity, and whether fingerprint unlock is on. They never leave the phone, and uninstalling ScreenBlock removes them.

Fingerprint unlock

If you turn on fingerprint unlock, Android performs the fingerprint check and only tells ScreenBlock whether it succeeded. ScreenBlock never receives or stores fingerprint data.

The optional DNS filter

ScreenBlock can walk you through setting a family-safe DNS server in Android's own network settings. This is optional, and the setting belongs to Android, not to ScreenBlock. Once it is on, your phone sends website lookups to the DNS provider you chose, under that provider's own privacy policy. ScreenBlock is not involved in those lookups and receives nothing from them.

3. Permissions ScreenBlock uses

Each permission is used only for the app's core function:

  • Screen capture (Media Projection) — to analyse what is on screen in real time. Frames are processed on the device and never stored or sent.
  • Display over other apps — to cover explicit content with an overlay.
  • Foreground service — to keep protection running in the background.
  • Notifications — to show that protection is running and to tell you if it has been paused.
  • Ignore battery optimisation — so Android does not shut protection down to save power.

4. This website

truthocean.app and screenblock.truthocean.app are static pages. They set no cookies and load no analytics, advertising, or tracking scripts. The site is hosted on Vercel, which, like any web host, processes basic request data such as IP addresses to deliver pages and protect against abuse. We do not use that data to identify or profile visitors.

If you email us, we use your message and address only to reply.

5. Third-party services

ScreenBlock includes no third-party analytics, advertising, or data-collection SDKs. Google Play handles downloads and updates under Google's own privacy policy.

6. Children's privacy

ScreenBlock is built to protect children and young people. It collects no data from anyone, of any age.

7. Changes to this policy

If this policy changes, we will update the date at the top of this page. We will never introduce data collection without disclosing it here first.
