blockApp Privacy Policy

Effective date: November 6, 2026 · Contact: support@timbuilds.dev

blockApp ("the app") is made by Tim of timBuilds, an independent developer. It blocks the apps and websites you choose, on schedules you set. It runs on Android, as a Chrome and Firefox extension, and on iPhone. This policy explains what it keeps and where.

The short version: blockApp keeps your setup on your own device. It has no server of its own, no ads, no analytics and no tracking, and nobody at timBuilds can see your information. It sends something off the device only if you turn on sync, and then only to a hidden folder in your own Google Drive.

What blockApp keeps on your device

You can see this on the app's "Your data" screen and delete past history there. Uninstalling blockApp, or removing the extension, deletes all of it.

What blockApp never keeps or sends

Android permissions and what they're used for

In Chrome and Firefox, the extension also notices whether the mouse and keyboard have been idle, for walk breaks, and saves nothing from it.

Website blocking

On Android, blockApp blocks websites with a filter that runs on the phone (Android shows it as a VPN). It checks only website names as they are looked up: names on your schedules get "no such site", and every other lookup goes on to your phone's usual lookup service, just as it would without blockApp. Nothing is recorded. In Chrome and Firefox, the extension compares the address of the page you open with your schedules, inside the browser.

Sync with Google Drive (optional)

Sync is off until you turn it on and sign in with Google. blockApp then asks Google only for access to its own hidden app folder in your Drive (the drive.appdata permission). It cannot see, open or change any of your other Drive files, your email or your contacts.

With sync on, each device copies to that folder: your schedules (names, apps, websites, days and times), earned-time settings, the times you started quick checks in the last day, how many minutes each schedule's apps were used this hour and today, and the minutes you earned today, plus a random device code and the codes of recently deleted schedules so deletions reach every device. Each device reads the other devices' copies so your limits match everywhere. Wi-Fi names and places are not sent.

That folder belongs to your Google account and is kept under Google's privacy policy. timBuilds has no access to it. To stop syncing, turn sync off in Settings. To delete the copies, open Google Drive settings, choose Manage apps, find blockApp, and choose Delete hidden app data, then Disconnect from Drive. You can also remove blockApp's access at any time at myaccount.google.com/permissions.

Use of Google user data

blockApp's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. blockApp uses this data only to keep your own devices in step. It is not sold, not used for ads, not shared with anyone, and not read by people.

App stores and platform services

blockApp is delivered through Google Play, the Chrome Web Store, Mozilla and Apple, which may collect information under their own policies. On Android, the Google Play services that handle "Sign in with Google" may send Google basic statistics about that sign-in. On iPhone, blocking runs through Apple's Screen Time on the device (the iPhone app is in testing).

Children

blockApp is not directed to children under 13 and does not knowingly collect information from them.

Changes

If this policy changes, the new version will be posted on this page with a new effective date.
