Privacy Policy

Last updated: May 11, 2026

This privacy policy covers all browser extensions and products published by Niranjan Akella ("we", "us", "our"). Currently this applies to Mindframe — Screen Time Tracker & Focus. As we release additional products, this policy will apply to them unless stated otherwise.

1. The Short Version

Our extensions track usage data locally in your browser. We do not collect your browsing history, page contents, IP address, email, or any personally identifiable information. The only data that leaves your browser is an anonymous device fingerprint (to prevent trial abuse) and license-validation calls if you upgrade to Pro.

2. Who We Are

Products are developed and maintained by Niranjan Akella, an independent developer based in Hyderabad, India. Contact: [email protected]

3. Data Stored Locally on Your Device

The following is stored exclusively in your browser's local extension storage and never leaves your device unless you explicitly export it:

  • The hostname of each website you visit (e.g. youtube.com) and time spent.
  • Daily and hourly time totals per hostname.
  • Your settings (theme, idle threshold, notification preferences).
  • Custom categories, site flags, and focus allowlists you configure.
  • The date you first installed the extension.

We do not collect URLs, query parameters, page contents, form input, cookies, or any data inside a website. We only know the hostname and how long it was on screen.

4. Data Sent to Our Backend

To prevent trial-period abuse, we send the following to our backend (hosted on Supabase) once per install:

  • An anonymous device fingerprint — a one-way SHA-256 hash derived from non-identifying browser settings. This cannot be reversed.
  • The trial start date.
  • Pro plan status and (if upgraded) a SHA-256 hash of your license key. The raw key is never transmitted.
  • The extension version number.

We do not store your IP address, email, name, or any other identifier alongside this data.

5. Payments (LemonSqueezy)

Payments are processed by LemonSqueezy. The extension communicates with LemonSqueezy's license API to validate and activate your license key. This is a direct browser-to-LemonSqueezy connection — we do not see or store your payment details. See LemonSqueezy's privacy policy.

6. Anonymous Analytics

We send a small number of anonymous, aggregated events (e.g. "popup opened", "trial started") to understand which features matter. These events contain no personally identifying information, browsing data, or website content.

7. What We Never Do

  • Sell or share your data with advertisers.
  • Read or transmit URLs, page contents, or form data.
  • Store your IP address.
  • Tie your data to an identity, account, or email.
  • Run remote code in the extension.

8. Your Rights

  • Export all locally stored data via Settings → Export JSON.
  • Delete all data via Settings → Clear all data.
  • Uninstall the extension at any time, which removes all local storage.
  • Request deletion of your device fingerprint by emailing us. We respond within 30 days.

9. Children

Our products are not directed at children under 13. We do not knowingly collect data from anyone in that age group.

10. Changes

If we change how our products handle data, we will update this page and the "Last updated" date above. Material changes will be reflected in the respective extension listings.
