Privacy Policy

Effective October 8, 2026

125x ("we") gives you AI summaries of YouTube videos. This policy explains what data we collect, how we use it, and your choices.

What we collect

Google account basics — your name, email address, and profile photo, via Google OAuth sign-in.
YouTube subscription list — read-only, via the youtube.readonly scope. We use it to build your personalized feed. We never modify your YouTube account, playlists, or subscriptions.
App activity — videos you open and save, stored on our servers keyed to your Google account ID so your Viewed and Saved lists sync across your devices.
Video transcripts — fetched from YouTube's public caption tracks to generate summaries and answer your questions.

How we use it

To build your personalized video feed and rank it by your interests.
To generate AI summaries (takeaways, action steps, lessons) and answer questions about videos. Transcripts are processed by Google's Gemini API, subject to Google's API terms.
To keep you signed in across visits (encrypted refresh tokens, 30-day sessions).

What we don't do

We don't sell your data or share it with advertisers.
We don't write to your YouTube account — our access is strictly read-only.
We don't collect your YouTube watch history beyond what you open inside 125x.

Google API compliance

125x's use of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.

Data storage & security

Data is stored on Cloudflare's infrastructure (KV storage). OAuth refresh tokens are encrypted at rest. Sessions expire after 30 days of inactivity; signing out deletes your server session immediately.

Your choices

Sign out any time — this deletes your server-side session.
Revoke access at myaccount.google.com/permissions — this instantly cuts our access to your Google data.
Delete everything — email us (below) and we'll delete your stored Viewed/Saved data and sessions.

Children

125x is not directed at children under 13, and we don't knowingly collect their data.

Changes

We'll post policy updates here and update the effective date.
