1. Introduction

Welcome to Stuloop. We are committed to protecting your personal information and your right to privacy. This Privacy Policy explains how we collect, use, and share your information when you use our mobile application and services.

2. Information We Collect

Account Information

When you register for Stuloop, we collect your email address, username, and password to create and secure your account. During registration, we also collect your date of birth.

Profile Information

You may choose to provide additional profile details such as a display name, bio, profile picture, and academic interests.

Uploaded Media & Content

We collect and store the videos and images you upload to share with study groups or the community.

Messages

We facilitate real-time messaging. Your messages are stored securely to provide chat history across your devices.

Social & Interaction Data

We collect information about your interactions on the platform, including likes, follows, comments, and content engagement. This helps us personalize your content recommendations and improve the relevance of what you see.

Device & Analytics Information

We automatically collect certain information about your device, including IP address, operating system, and app usage data to improve our services and fix bugs.

Calls, Microphone & Camera

Stuloop supports voice and video calls over the internet. While you are on a call we access your microphone (and your camera, for video calls) so that audio and video can be transmitted to the person you are talking to. Call audio and video are transmitted in real time and are not recorded, listened to, or stored by us. We do store limited call metadata — who called whom, the call type (voice or video), start time, duration, and whether the call was missed or declined — so we can show your call history, deliver missed-call notifications, and keep the service secure.

Notifications & Device Identifiers

To deliver calls, messages, and notifications while the app is closed, we use Firebase Cloud Messaging (Google). This requires us to store a device push token — a random identifier generated by Google for your device and app installation — together with your account. Tokens are rotated or removed when you log out or delete your account. We also store your notification and ring preferences so your settings follow you across devices.

Permissions We Request

• Microphone and Camera — for voice and video calls, used only while a call is active.
• Notifications and full-screen notifications — so calls and messages arrive instantly, including the incoming-call screen when your phone is locked.
• Photos and videos — only for the content you choose to upload or send in chat. Stuloop never reads files or documents on your device.
• Bluetooth — to route call audio to your Bluetooth headset or car.
• Background battery settings — we open your phone's battery optimization settings screen so you can optionally exempt Stuloop from battery optimization. The choice is always yours and the app works without it.

3. How We Use Your Information

• To provide, operate, and maintain our application.
• To enable study groups, content sharing, and real-time messaging.
• To personalize your AI learning experience and content recommendations.
• To communicate with you about updates, security alerts, and support messages.

4. Cloud Storage and Data Security

Your data, including uploaded media and messages, is securely stored on industry-standard cloud infrastructure. We implement appropriate technical and organizational security measures designed to protect the security of any personal information we process.

5. Third-Party Service Providers

We share the minimum necessary data with the providers that run our infrastructure: Google Firebase Cloud Messaging (delivery of call and message push notifications) and our secure cloud backend and hosting providers (storage and content delivery for the data described above). We do not sell your personal information and we do not share it with advertisers.

6. Data Retention

We keep your information for as long as your account is active or as needed to provide you services. Chat messages follow our retention lifecycle: after delivery they are kept in a limited window so they can be synced to your other devices, after which message content is removed from our servers and only non-identifying delivery metadata remains. Call history entries are retained while your account is active. When you delete your account we permanently delete your profile, media, messages, and call history from our active servers (see our Delete Account page), and remove them from backups within 30 days, unless a longer retention period is required by law.

7. Your User Rights

Depending on your location, you may have rights to access, correct, update, or request deletion of your personal information. You can exercise these rights from inside the app or by writing to us at the address below.

8. Account & Data Deletion

You can delete your account and all associated data permanently directly from the app by navigating to Settings → Account → Delete Account. If you no longer have access to the app, you can request deletion by emailing support@stuloop.com from your registered email address. Please see our Delete Account page for full details of what is deleted and what (if anything) is retained.
