Reader privacy policy
Effective date: 12 November 2026
Reader is a Chrome extension that translates, summarises or turns technical articles into a checklist of steps. This page explains exactly what it handles. The short version: Reader sends the article you ask about to our server and to Anthropic's Claude to do the work. It keeps your username, your history and some daily counters. It has no ads and no analytics, and it never sells data.
What Reader stores on your device
- A random install ID. Created the first time Reader runs. It is not linked to your name, email or Google account. It works like a key: whoever has it can use your Reader profile.
- Your username, your language and mode choices, and your theme (System, Light or Dark).
- The article on the current tab, while the browser is open, so the side panel can show it. It is removed when the tab closes or navigates away, and when Chrome closes.
What Reader sends, and when
When the side panel opens, Reader sends your install ID to our server to load your profile. Article content never leaves your device until you press Translate, Summary, Steps or Regenerate. Then Reader sends this to our server:
- your install ID;
- the article's address (URL) and its text, with the language and mode you picked;
- when a result finishes: the article's title, site name and the result, so it can be saved to your History.
When you pick a username, Reader sends the username and your install ID. While you type, it checks whether the name is free.
What our server keeps
| What | Why | How long |
|---|---|---|
| Install ID and username | Your profile | Kept indefinitely |
| Article URLs you used Reader on, per month | Usage count and History | Kept indefinitely |
| History: article URL, title, site, mode, language and the result | So you can reopen past results | Kept indefinitely |
| Shared result cache: the result, with mode and language, keyed by a fingerprint (hash) of the article text | So the same article in the same language is not processed twice | Kept indefinitely. It holds no install ID, username or URL |
| Daily counters per install ID, per IP address, and in total; sign-ups per IP address | Fair-use limits that stop abuse | Kept indefinitely for now |
IP addresses: the daily counters are stored against your IP address as it reaches our server, in plain form, next to the date and a count. They are used only to enforce the daily fair-use limits.
Our hosting provider also keeps short-lived technical request logs, as any web server does.
Who processes the data
- Supabase hosts our database and server functions, in its Tokyo, Japan (ap-northeast-1) region. Supabase privacy policy
- Anthropic runs the Claude model that writes the translation, summary or steps. It receives the article text and your chosen language and mode, not your install ID, username or IP address. Anthropic processes it under its commercial terms, which do not allow training on this data by default. Anthropic privacy policy
We use no other services. No ads, no analytics, no tracking, and we never sell or share your data for any other purpose.
Reading pages automatically (optional)
Without that permission, Reader reads a page only after you click its icon (or press Alt+Shift+R). While the side panel stays open, it also reads the next pages you open on the same site in that tab, because Chrome keeps the access your click gave for that site. A page on another site needs another click. That text stays in your browser too.
If you turn on “Read pages automatically”, Chrome asks for permission to read the sites you visit. With it, the open side panel reads the article on each page you visit so it is ready when you want it. That text stays in your browser. Nothing is sent until you press a button, and nothing is read while the side panel is closed. You can remove the permission at any time from the extension's details page in Chrome.
Data retention
We do not delete data stored on our server. Your profile, History, usage records and cached results are kept indefinitely, and there is no in-app delete option. Uninstalling Reader removes everything stored on your device, but not what is on our server. If you have questions about your data, email to@allahabadi.dev.
Price and limits
Reader is free for now, with daily fair-use limits.
Children
Reader is made for software engineers and is not directed at children under 13. We do not knowingly collect data from them.
Changes
If this policy changes, we will update this page and its effective date. If a change affects what data Reader collects, we will say so in the extension's store listing before it takes effect.
