Acropolis privacy policy

Acropolis is a new tab extension for Chrome and other Chromium browsers, made by Yury Molodtsov. It has no servers and no user accounts. It runs in your browser and talks directly to the services below. Nothing is sent to me or to anyone else.

Google Calendar

If you connect Google Calendar, Acropolis asks Chrome’s built-in Google sign-in for read-only access to your calendars (calendar.readonly). It uses that access only to show your events for today and tomorrow on the new tab page.

• Event titles, times, locations, meeting links and calendar links go straight from Google to your browser.
• Chrome keeps the access token, as it does for any extension that uses Google sign-in. Acropolis keeps a copy of your events in your browser’s extension storage so the page loads instantly. That copy stays on your device.
• Acropolis never sends your calendar data anywhere else. It doesn’t sell it, use it for advertising, or use it to train AI models, and no person reads it.
• Acropolis can’t create, change or delete events.

Acropolis’s use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.

Readwise and Instapaper

If you add a Readwise or Instapaper access token, Acropolis stores it in your browser’s extension storage. It uses the Readwise token only to fetch your daily review, and the Instapaper token only to fetch your newest saved articles. Your tokens, highlights and saved articles aren’t sent anywhere else.

Other features

• Weather: the city you enter, or your approximate coordinates if you leave it empty, goes to Open-Meteo for the forecast. Coordinates also go to BigDataCloud to look up your city’s name.
• Icons: the web addresses of your bookmark tiles and the sites of your Instapaper saves go to Google’s favicon service to fetch their icons.
• Bookmarks bar: if you turn it on, Acropolis reads your browser’s bookmarks to show them on the page. They never leave your browser.
• Now playing: if you turn it on, Acropolis checks which tab is playing audio and reads the track title, artist and artwork that page publishes, so it can show them and pause or resume playback. It doesn’t read anything else on the page, and the information stays in your browser.
• Search: what you type goes to your default search engine, or to the AI service you chose, only when you submit it.

What stays in your browser

Your note, cached calendar events, daily review and Instapaper saves, and your Readwise and Instapaper tokens stay in your browser’s local extension storage. Your settings and bookmark tiles sync through your browser account if browser sync is on.

Removing your data

• To disconnect Google Calendar, open the Acropolis settings and click Disconnect. Chrome forgets the token, and Acropolis asks Google to revoke it. You can also remove access at myaccount.google.com/connections.
• To remove a Readwise or Instapaper token, clear its field in settings and save.
• Uninstalling the extension deletes everything it stored on your device.
