Privacy Policy
Glassmode browser extension · Effective August 30, 2026
Glassmode restyles websites inside your browser. It has no account, no sign-in, and no server of ours for it to talk to. This policy is short because there is genuinely very little to disclose.
What Glassmode stores, and where
| What | Where it lives | Does it leave your device? |
|---|---|---|
| Your settings — which sites are glassed, intensity, theme, accent colour, motion level, per-site adjustments | Your browser's own extension storage (the syncing kind) | Only through your own browser profile sync, between your own devices. Never to us. |
| Your Pro license key, if you buy Pro | The same settings store | Sent to Lemon Squeezy to check it is valid — see below. Nowhere else. |
| A backdrop image, if you choose one | Local storage on that computer only | No. It is never uploaded anywhere, including to us. |
The pages you visit
To decide which parts of a page should become glass, Glassmode reads that page’s layout and colours — where the navigation bar is, how large a card is, whether the text behind the glass would still be readable. All of that happens inside your browser, as the page renders, and is discarded immediately.
Glassmode does not record, store, or transmit the pages you visit, their content, their addresses, or your browsing history. There is nowhere for it to send them: we operate no server for this extension.
The only network request it ever makes
Exactly one. When you enter a Pro license key, the extension sends that key to Lemon Squeezy’s public license-validation endpoint (api.lemonsqueezy.com) to confirm it is real. That request contains the license key and nothing else — no identifier, no page data, no usage information.
If you never buy Pro, Glassmode makes no network requests at all.
Purchases
On Chrome, Lemon Squeezy is the merchant of record. They run the checkout and handle payment details; we never see your card number. On the Mac App Store, Apple handles the purchase in the same way. We receive no payment information from either.
No tracking, no exceptions
Glassmode contains no analytics SDK, no telemetry, no advertising, no trackers, and sets no cookies. There is no account and no sign-in. We collect nothing, so there is nothing to sell, share, or lose in a breach — and nothing is sold or transferred to anyone.
Deleting your data
Remove the extension and everything it stored goes with it. Settings that travelled through your browser profile sync clear when you clear that profile’s synced data.
Children
Glassmode is not directed at children and collects no personal information from anyone, including children.
This website
Separately from the extension, stackcurious.com counts page views using cookieless, aggregate analytics. It does not identify you, does not follow you across sites, and has no connection to the extension or to the pages you browse with it.
Changes
If any of the above changes, this page and its effective date change with it.
