Clarix is designed with privacy in mind. We collect only what is necessary to provide the service and never sell your personal data to third parties.
1. Who we are
Clarix ("we", "our", "us") is an iOS application developed and operated by Ahsan. If you have any questions about this policy, contact us at clarix@haaa.in.
2. Information we collect
Account information
- Name and email address (required to create and identify accounts)
- Role (Teacher, Student, or Parent)
- Password (stored only as a one-way hash on our server — we never see your plain-text password)
Content you create
- Assignments, quiz questions, grades, and feedback
- Announcements and school updates
- Voice notes and audio recordings
- Photos attached to submissions, assignments, or announcements
- Messages sent through the in-app chat
- Schedule events
Device and usage information
- Apple push notification token — used only to send push notifications to your device
- Crash and performance reports — if the app crashes or freezes, it sends a technical report (app and iOS version, device model and the error details) so we can fix the problem. Reports contain no messages, photos or school work and are deleted after 30 days.
- Calendar and widgets — if you turn on calendar sync, Clarix adds classes, events and due dates to a "Clarix" calendar on your iPhone. Widgets and Siri answers use a copy of your schedule stored on your device. None of this is sent to us.
3. How we use your information
- To provide and operate the Clarix service
- To send push notifications about assignments, grades, and messages
- To allow teachers to manage their class, students, and content
- To allow parents to follow their child's progress
- To improve app performance and fix issues
4. Data storage and security
All data is stored on Clarix's own servers at clarix.haaa.in (database and file storage), on servers rented from our web hosting provider. Data is encrypted in transit (TLS). Every request is checked on the server so users can only access data from their own class, and photos and voice notes are only reachable through signed private links.
To protect against data loss, the database and uploaded files are backed up every day. Backups are kept on the server for up to 4 weeks, and an encrypted-in-transit copy is kept on the developer's own computer and iCloud storage for up to 90 days. Backups are only used to restore Clarix after a failure.
5. Who can see your data
- Teachers can see their own students' names, submissions, grades, and progress.
- Students can see their own assignments, grades, and feedback.
- Parents can see their linked child's schedule and progress.
- No user can see data from a different teacher's class.
- We (Ahsan / Clarix) do not read individual user content except when required to investigate a reported issue.
6. Third-party services
Clarix uses the following third-party services:
- Our web hosting provider — runs the servers that store Clarix data; it does not use your data for its own purposes
- Apple Push Notification Service (APNs) — delivery of push notifications on iOS
- Sign in with Apple — if you choose it, Apple confirms your identity and shares your name and email (or a private relay email) with Clarix
- Apple App Store / StoreKit — subscription purchases are processed directly by Apple; we never see or store your payment details
We do not integrate advertising networks, social media trackers, or analytics tools. Crash reports go only to Clarix's own server.
7. Children's privacy
Clarix may be used by students who are minors. Student accounts are created exclusively by teachers and are not publicly accessible. We do not knowingly collect personal information from children without appropriate consent from a teacher or school authority. If you believe a child's data has been collected without appropriate authorisation, contact us at clarix@haaa.in.
8. Data retention and deletion
Teachers can delete all class data (assignments, submissions, announcements, grades) at any time from within the app. When a teacher deletes their account, all associated data — including enrolled student and parent accounts and all uploaded files — is permanently deleted from our servers.
Students or parents wishing to delete their data should contact their teacher or email us directly.
Deleted data disappears from the app straight away and from backups within 90 days, as older backups are removed.
9. Your rights
Depending on your location, you may have the right to:
- Access the personal data we hold about you
- Request correction of inaccurate data
- Request deletion of your data
- Object to or restrict processing of your data
- Data portability
To exercise any of these rights, contact us at clarix@haaa.in.
10. Changes to this policy
We may update this Privacy Policy from time to time. We will notify users of material changes via the app or by email. Continued use of Clarix after changes constitutes acceptance of the updated policy.
