HISN is an independent application developed by a member of the American Muslim community. It is not a corporation, it is not funded by venture capital, and it is not designed to profit from your data.

| Family link and device record | A six-character linking code, which apps or categories are restricted, schedules (prayer, bedtime, school, Quran time), daily limit, whether protection is on, and when the child's phone was last seen online | So changes a parent makes reach the child's phone |
| Installed apps list (Android child devices only) | The names and package names of apps installed on the child's phone | So the parent can choose which apps to restrict |

| Data | Why we need it |

| Apple Screen Time selection (iPhone) | The apps chosen in Apple's picker stay on the phone that chose them |
HISN's Accessibility Service detects when a restricted app is opened and closes it, prevents access to settings that would disable HISN, and applies your schedules. It does NOT read or record what you type, access messages or content, take screenshots, or monitor browsing history. The name of the app currently on screen is processed on the device and is not sent to our servers.
On iPhone, HISN uses Apple's Family Controls, Managed Settings and Device Activity frameworks. Apps are chosen on the phone being managed, in Apple's own picker. Apple gives HISN only anonymous tokens for that choice: HISN cannot see which apps were chosen, and the tokens never leave the device. Restrictions are applied by iOS itself.
HISN requests Device Administrator permission so a child cannot uninstall it. It does NOT allow HISN to wipe your device or enforce password policies, and a parent can revoke it at any time from HISN's Settings.
HISN calculates Salah times using the Aladhan API (aladhan.com). The app sends the coordinates of the city you selected — not your real GPS location — and no personal information.
HISN is set up by a parent. A child's phone is linked with a code the parent creates; the child does not create an account, and does not enter a name, email address or any other personal information. The child's phone signs in with an anonymous identifier so that only that phone and the parent's account can read or change its record. The information kept about a child's device is listed in section 2 and is visible only to the linked parent.
A parent can delete all of it at any time by deleting their account in the app (section 9). HISN does not knowingly collect personal information from children under 13 beyond what the parent sets up, and complies with the Children's Online Privacy Protection Act (COPPA).
Server data is protected by access rules: a device record can be read only by the parent who created it and the child phone linked to it; a partnership only by its two members.
| Service | Purpose | Data shared |
|---|---|---|
| Google Firebase (Authentication, Firestore, Cloud Messaging) | Accounts, syncing between phones, notifications | The data listed in section 2 |
| Netlify | Runs the small server functions that send notifications and partner invitations | The notification or invitation being sent; nothing is stored |
| Resend | Delivers the partner invitation email | The partner's email address and the inviter's email address |
| Aladhan API | Prayer time calculation | City latitude/longitude only |
| Apple App Store / Google Play | App distribution | Standard store analytics. See their privacy policies. |
We do not use any advertising networks, analytics platforms, or data brokers.
You can delete your account from inside the app: Settings → Delete Account (Parent and Self-Control modes) or Delete Account at the bottom of the Partner screen. This permanently deletes your account, your family link and child device records, the prayer log, your partnerships, your own requests, and your notification token. It takes effect immediately and cannot be undone.
If you cannot use the app, email hisnapp@gmail.com from the address on your account and we will delete it for you within 30 days. You may also ask us for a copy of the data held about your account.
If we make material changes to this Privacy Policy, we will update the Effective Date at the top of this page and notify users through the app. We will never make changes that reduce your privacy protections without clear advance notice.
