Privacy Policy

Last updated: March 2026

Enso ("the App") is developed by Pradep Kumar Chinnasaamy ("I", "me", or "my"). Your privacy matters. This policy explains what data is collected, how it is used, and what stays on your device.

1. Information We Do Not Collect

Enso does not collect, store, or process any personal information. The App does not require account creation, login, or any form of registration. No name, email address, phone number, or other personally identifiable information is collected.

2. On-Device Data

All app data — including your blocking rules, Focus entries, schedules, app selections, usage preferences, and cached usage insights — is stored locally on your device using Apple's on-device storage (UserDefaults within an app group). This data never leaves your device and is not transmitted to me or any third party.

3. Screen Time & Usage Data

Enso uses Apple's Screen Time API (FamilyControls, DeviceActivity, and ManagedSettings frameworks) to provide app blocking and usage insights. All screen time data is processed entirely on your device by Apple's frameworks.

I do not have access to, collect, or store any information about which apps you use or how long you use them.
Usage analytics and AI insights are computed on-device and stored locally.
App blocking is enforced natively by iOS — no VPN, proxy, or DNS manipulation is used.
The App uses the .individual authorization scope — it manages only your own screen time, not family members'.

4. Strict Mode & PIN Security

If you enable Strict Mode with a PIN, the PIN hash (SHA-256) is stored securely in your device's Keychain. It is not synced via iCloud Keychain and never leaves your device.

5. On-Device AI

On supported devices (iOS 26+), Enso uses Apple Intelligence (Foundation Models) to generate usage insights. All AI processing happens entirely on your device. No usage data is sent to any server for AI processing.

6. Analytics & Crash Reporting

Enso uses Firebase Analytics and Firebase Crashlytics (provided by Google) to collect anonymous, aggregated data. This includes:

App launch and session data
Feature usage patterns (e.g., which screens are visited, blocks created)
Crash reports and diagnostic logs
Device type, operating system version, and app version

This data is anonymous and cannot be used to identify you personally. The following privacy controls are applied:

Ad personalization signals: disabled
Ad storage, ad user data, and ad personalization consent: denied
No data is shared with advertisers, data brokers, or any other third parties for advertising purposes

Analytics data is used solely to understand how the App is used and to improve its stability and performance.

7. Subscriptions

The App offers optional premium subscriptions managed through RevenueCat and Apple's App Store. RevenueCat processes subscription status and purchase validation. I do not collect or have access to your payment information. Please refer to Apple's Privacy Policy and RevenueCat's Privacy Policy for details on how they handle your purchase data.

When your subscription expires, premium features become unavailable, but free features and your existing data remain accessible.

8. Third-Party Services

The App uses the following third-party services:

Firebase Analytics & Crashlytics (Google) — anonymous usage analytics and crash reporting
RevenueCat — subscription management and purchase validation

No other third-party SDKs, advertising frameworks, or tracking tools are used.

9. Data Retention

Since all app data is stored locally on your device, you have full control over it. You can delete all app data by deleting the App from your device. Anonymous analytics data stored by Firebase is retained according to Google's standard retention policies and cannot be linked back to you.

10. Children's Privacy

The App does not knowingly collect any personal information from anyone, including children. Since no personal data is collected and no account is required, the App can be used by individuals of any age.

11. No Account Required

Enso requires no account, no sign-in, and no email address. There is no user profile and no cloud sync.

12. Permissions

Enso requests the following permissions:

Screen Time (Family Controls) — required to block apps and monitor usage, using the individual authorization scope
Notifications — optional, used to alert you when blocked apps are accessed

13. Changes to This Policy

If this policy is updated, the date at the top of this page will be revised. Continued use of the App after changes constitutes acceptance of the revised policy.
