In short
Astro21 sets no cookies and runs no trackers. It keeps your sign-in and a few settings in your browser, listed below with how to remove each one.
1. What Astro21 keeps in your browser
Astro21 sets no cookies of its own and runs no advertising trackers. Its page-view and page-speed counting sets no cookies and stores nothing on your device. It uses your browser’s local storage for the items below, and nothing else. Except the sign-in session, they stay on your device.
| Item | What it holds | Why | How long | How to remove it |
|---|---|---|---|---|
sb-…-auth-token | Your sign-in session: access codes, your account ID and the phone number or email you sign in with. The middle of the name is our database project’s code. | Keeps you signed in. It is sent to our servers with each request so we know it is you. | Until you sign out. It renews itself while you use the app. | Sign out. |
astro_theme | “day” or “night”. | Remembers the display you chose. | Until you choose “Match phone” again. | Choose “Match phone” in More. |
astro_language | Your language, for example “hi” for Hindi. | Shows Astro21 in your language, even before you sign in. | Until you clear it. | Clear site data in your browser. |
astro_current_place:v1:guest | The current place you chose while signed out: its name, map position (rounded to about 1 km if it came from your device) and time zone. | Hora, panchang and muhurat for where you are. | Until you remove the place. | Clear site data in your browser, or choose “Use birth place” where it is shown. |
astro_current_place_device:v1:<account ID> | When signed in: a note that your saved current place came from this device’s location, with its rounded position and time zone. | Stops the app suggesting a time-zone change you have already dealt with. | Until you change or remove the place. | Choose another place, or clear site data. |
astro21.match.v1 | Your Kundli Milan entries: both names, birth dates, times and places, and who is the groom or bride. | So you do not have to type them again. | Until you remove them. | Press “Clear both” on the matching form. |
last_weekly_dl_<account ID> and last_monthly_dl_<account ID> | The time you last printed your weekly or monthly reading. | A record of printing on this device. It is not sent to us. | Until you clear it. | Clear site data in your browser. |
astro21.reloaded | The time the app last reloaded itself to load a new version of Astro21. | After an update, a page that was already open reloads once to get the new version; this stops it reloading again and again. | Until the next such reload replaces it. | Clear site data in your browser. |

2. Storage by other services
- Payment window. When you pay, our payment processor’s window opens on the page. It may set its own cookies or storage, for example to keep the payment secure and prevent fraud. Its own policy applies.
- Fonts. The app’s fonts load from a web font service. That sets no cookies, but your browser sends the service your IP address and browser details.
- Permissions. If you allow location or the microphone, your browser remembers that choice itself. Change it in your browser’s site settings.
3. Why there is no cookie banner
Everything listed above is needed for the app to work or remembers a choice you made. None of it tracks you or is used for advertising, so there is nothing to accept or decline. If we ever want to add advertising, or analytics that use cookies or identify you, we will ask for your consent first and update this page.
4. How to clear everything
In your browser’s settings, find the site settings or site data for astro21.io and clear it. This signs you out and removes all the items above. Data saved with your account is not affected; to delete that, see Delete your account.
