TimeFence — Privacy Policy

Overview

TimeFence is a time-based DNS blocker for Android that operates entirely on your device. It uses Android's VPN API to create a local VPN that intercepts DNS queries and blocks domains according to your configured schedules.

All processing happens locally on your device. No data is sent to external servers. Your privacy is our highest priority.

Data We Access

TimeFence accesses the following data, all processed locally on your device:

DNS queries — intercepted by the local VPN to evaluate against your block rules in real-time. Queries are never recorded or sent externally.
Block rules & schedules — the domains, time windows, and days-of-week you configure.
Presets — named groups of block rules you create or customize.
Block event statistics — counts and timestamps of blocked queries, stored locally for your personal stats dashboard.

Data Storage

All information is stored exclusively on your device using:

SQLite database — block rules, schedules, presets, and blocking statistics.
SharedPreferences — app settings such as snooze state, PIN lock, language preference, theme, and onboarding completion.

No data is ever transmitted to any server. All data resides within the app's private storage area protected by Android's application sandbox.

Data We Do Not Collect

TimeFence does not collect, transmit, or store any of the following:

Personal identifiers (names, email addresses, phone numbers)
Location data
Device identifiers or fingerprints
Browsing history beyond aggregated block counts
Network traffic content — the VPN only evaluates DNS domain names
Third-party analytics or advertising data

Data Sharing

TimeFence does not share any data with third parties. The only external service involved is Google Play Billing, which handles subscription payments. Google Play does not have access to your browsing data, block rules, or any app-specific information.

Data Retention & Deletion

All data is stored locally and remains on your device until you choose to remove it. You can delete all TimeFence data by:

Clearing app data via Android Settings > Apps > TimeFence > Clear Data
Uninstalling the app — this permanently removes all local data

Both methods permanently and irreversibly delete all stored information.

Data Security

Your data is protected by:

Android application sandboxing — the app's private storage is inaccessible to other applications.
Local VPN tunnel — DNS queries are evaluated on-device and never transmitted to external servers.
No network transmission — since no data leaves your device, there is no risk of interception in transit.

Permissions

TimeFence requires the following Android permissions, each justified by core functionality:

VPN Service Creates the local VPN tunnel that intercepts DNS queries for domain blocking. No traffic leaves the device.

Foreground Service Keeps the VPN service running persistently so blocking remains active in the background.

Exact Alarms Triggers schedule transitions at precise times so blocking starts and stops exactly when configured.

Boot Completed Automatically restarts the VPN service after a device reboot to maintain uninterrupted protection.

Notifications Displays the persistent notification required by Android for foreground services, showing VPN status.

In-App Purchases

TimeFence offers an optional Pro subscription managed entirely by Google Play. The developer does not have access to your payment information, billing address, or Google account details. All subscription management (purchase, cancellation, refunds) is handled through the Google Play Store.

Third-Party Services

The only third-party service integrated into TimeFence is Google Play Billing, used solely for processing subscription payments. Google Play Billing is governed by Google's Privacy Policy.

No other third-party SDKs, analytics platforms, or advertising networks are used.

Children's Privacy

TimeFence is not directed at children under the age of 13. We do not knowingly collect any personal information from anyone, including children. Since no personal data is collected from any user, there is no risk of inadvertent collection from minors.

Changes to This Policy

We may update this privacy policy from time to time. Any changes will be reflected in the "Last updated" date at the top of this page. Continued use of TimeFence after changes constitutes acceptance of the revised policy.
