Precap – Privacy Policy
What Precap does
Precap is a browser extension that summarizes YouTube videos and checks titles for clickbait. It runs on youtube.com and shows two buttons when you hover over a video thumbnail.
What is processed – and when
Nothing is sent anywhere until you click a Precap button. Then, for that one video:
| Data | Why | Where it goes |
|---|---|---|
| Video ID, title, channel name, transcript (or description if there is no transcript), language code | To create the summary and clickbait check | Precap server, then Google Gemini API |
| A random installation ID (created on install, not linked to you) | To count the free summaries and to link a Precap Pro purchase to your installation | Precap server |
| Your IP address | To prevent abuse of the free tier | Precap server – stored only as a salted, one-way hash |
Precap does not read or send your YouTube account, watch history, search history, cookies, comments, or any page other than the video you clicked.
What is stored, and for how long
- Summaries are cached on the Precap server for up to 30 days so that other people asking for the same video get an instant answer. A cached summary contains only information about the public video, nothing about you.
- Daily counters (random installation ID and hashed IP address with a count per day) are deleted after 7 days.
- Free-summary total (installation ID with the number of free summaries used so far) is deleted after one year without use.
- Precap Pro: if you buy Pro, we store a hash of your activation code, the Stripe checkout session ID, the validity period and the installation IDs where the code was activated. We do not receive or store your name, email address or payment details – those are processed by Stripe. These records are deleted 90 days after your Pro period ends.
- Uninstall feedback: if you pick a reason on the page that opens after uninstalling Precap, only the reason, the extension version and the date are stored (kept for up to one year).
- Aggregate statistics: total numbers per day (summaries created, summaries served from cache) – no data about individual users – are kept for up to one year.
- Technical logs kept by our hosting provider (Cloudflare) for operation and debugging may include request metadata such as IP addresses; they are deleted automatically after a few days.
- In your browser (chrome.storage, never leaves your device except as described here): your settings, the installation ID, your optional own Gemini API key, and recent summaries for up to 7 days. Use “Clear cache” in the Precap popup or uninstall the extension to delete them.
Using your own Gemini API key (optional)
If you enable “Use my own Gemini API key”, the video data described above goes directly from your browser to the Google Gemini API using your key, without passing through the Precap server. Your key is stored only in your browser and sent only to Google. Google’s terms for your key apply; on Google’s free tier, Google may use inputs to improve its products.
Service providers
- Cloudflare, Inc. – hosts the Precap server (Cloudflare Workers) and its database (located in Western Europe).
- Stripe – processes Precap Pro purchases as merchant of record (payment, invoice, taxes, refunds) under its own privacy policy. Stripe only tells the Precap server that a checkout was paid and which installation ID it belongs to.
- Google LLC – generates the summaries via the paid Gemini API. Under Google’s terms for paid services, inputs are not used to train Google’s models.
Data is not sold, not shared for advertising, and not used for anything other than providing Precap.
Your rights
Precap does not store data that identifies you directly. If you have questions or want to exercise your rights under the GDPR (access, deletion, objection), contact us at the address below. You can also delete all locally stored data at any time by uninstalling the extension.
Children
Precap is not directed at children under 18.
Changes
If this policy changes, the date at the top is updated. Significant changes are announced in the extension’s Chrome Web Store listing.
