Privacy Policy

The Short Version

We don't collect your data. Period. Osmomark runs entirely in your browser. The AI models are loaded locally via WebAssembly. No text you read is ever sent to a server — not for analysis, not for logging, not for "improving our models."

What We Collect

Nothing from your browsing. Osmomark processes all text locally in your browser's JavaScript runtime. We have no servers that receive your page content, highlights, or reading patterns.

The only data we ever receive is:

• License keys — If you purchase Pro, your license key is validated against our API. The key alone is sent (no device info, no reading data).
• Anonymous install count — The Chrome Web Store provides basic download statistics. This is aggregate, non-identifying data.

What We Store Locally

Osmomark uses chrome.storage.local for:

• Extension settings (enabled categories, highlight style, colors)
• Deep NER model weights (~18MB cached in IndexedDB)
• Pro license status (cached with 7-day offline grace period)
• Daily deep scan usage counter (resets daily, stored locally only)

Chrome Permissions

The extension requests activeTab and storage permissions only. activeTab lets Osmomark read the text of the currently active tab when you click the icon — no background surveillance. storage is used for settings and model caching.

Third-Party Services

Osmomark does not embed analytics, trackers, or third-party scripts on any pages it processes. The extension loads its NLP runtime (transformers.min.js) from the extension's own bundled files — no CDN calls, no external fetch.

Payments

Pro subscriptions are processed by Lemon Squeezy. We never see or store your payment details. Lemon Squeezy's privacy policy applies to payment processing.

Changes to This Policy

If we update this policy, we'll update the "Last updated" date and post a notification in the extension's popup. We'll never materially change our data practices without notice.
