Privacy Policy
Sai Tamil Aarti (Android app, package com.techsa.saiaarti)
Last updated: 4 November 2026
The short version. The app has no account, no ads, no analytics and no tracking. The Aarti recordings and lyrics are inside the app and play without internet. The app only goes online if you use Group Aarti, and then it sends only what a group needs to work: the name you type, the groups you are in, and a notification token.
What stays on your phone
Your settings (language, theme, lyrics text size), reminder times, sleep timer and where you stopped listening are stored only on your device. They are never sent to us.
Daily Aarti reminders are scheduled by the phone itself; they do not use the internet.
Group Aarti (optional)
If you create or join a prayer group, the app talks to a small server we run on Cloudflare Workers, so that the group's admin can start an Aarti for everyone and members can be notified. Nothing is sent unless you create or join a group.
The server stores, for each group:
- the group's name and its 6-letter invite code;
- for each member: the name you type when you join (it does not have to be your real name), a random member id created on your phone, a scrambled (hashed) form of a random secret that proves the id is yours, the time you joined, and a Firebase Cloud Messaging token so the group's notifications can reach your phone;
- who the admin is, how many minutes before an Aarti members are notified, and the Aarti the admin has started or scheduled (which song, when it starts, and who started it).
Every member of a group can see the group's name and the names of its members. Anyone who has the invite code can join the group, so share the code only with people you want in it.
We do not ask for, and the server does not store, your phone number, email address, contacts, location or any account details.
As with any website, Cloudflare processes your IP address to deliver the traffic, and may keep short-lived technical logs. See Cloudflare's privacy policy.
Notifications
Group notifications are delivered by Google's Firebase Cloud Messaging. To do this, Google gives the app a token for your device, which the app sends to our server as described above. Google processes the token and the notification under Google's privacy policy. The notification contains only the group's name, the Aarti and its time.
You can turn notifications off for any group in the app (Groups → the bell), or for the whole app in your phone's settings.
Permissions
- Notifications: for daily reminders and group notices. Optional.
- Internet: used only for Group Aarti.
- Play in the background (foreground media service): so the Aarti keeps playing with the screen off and shows the player in the notification panel.
- Run at start-up: to set your reminders again after the phone restarts.
The app keeps the screen awake while an Aarti is playing and the app is open. It does not use the camera, microphone, location, contacts or your files.
Backups
If Android backup is turned on in your phone's settings, Android may include this app's settings and group membership in your device backup with Google. This is controlled by your phone and your Google account, not by the app.
Deleting your data
- Leave a group (Groups → the group → Leave this group): your member record, name and notification token are deleted from the server straight away. When the last member leaves, the whole group is deleted.
- Uninstalling removes everything the app stored on your phone. It cannot tell the server, so leave your groups first. If you have already uninstalled, email us the group code and the name you used, and we will remove you.
Sharing and selling
We do not sell, rent or share your information with anyone, and we do not use it for advertising. It is used only to run Group Aarti.
Children
The app is suitable for all ages. It does not knowingly collect personal information from children; Group Aarti asks only for a display name, which can be anything.
Changes
If this policy changes, the new version will be published at this address with a new date at the top.
