Privacy Policy
Privacy Policy
Effective date: July 21, 2026 · Last updated: July 26, 2026
The whole policy in one line: Sider has no accounts, no servers, and no analytics. It cannot send your data anywhere, because it contains no code that transmits anything.
CS42.org ("we", "us", "our") built the Sider app as a free application. This page explains what the App stores, where it stores it, and how to delete it.
1. What We Collect
Nothing. We operate no servers and receive no data from the App. We cannot see your videos, your answers, your profile, or how often you play.
2. What the App Stores on Your Device
- Reaction videos and audio you record during a session.
- Your answers — the slider position, how long you took, and how many times you changed direction.
- Profile details you choose to enter — a display name, optional social handles, an optional profile photo, and optionally a birth year, a birthday, and a country.
- Preferences such as your recording mode and sound settings.
All of it lives in the App's own storage on your iPhone. None of it is transmitted.
3. Camera and Microphone
The camera and microphone are used only while a session is actually recording, and only in the recording modes you choose. In "audio only" mode the camera is not used at all. In "no recording" mode neither is used. Footage is written directly to your device.
4. Photos
When you export a reaction video, the App asks iOS to save it to your Photos library. It requests permission to read your Photos library only if you later ask it to play back a video that you chose not to keep a second copy of inside the App. The App does not browse, index, or upload your photo library.
5. Sharing Is Always Your Choice
Nothing is shared automatically. When you tap share, iOS hands the file to whichever app you pick, and from that point that app's privacy policy applies. A video you post publicly is public — please think about who else is in frame.
6. No Tracking, No Ads, No Third-Party SDKs
The App contains no advertising, no analytics, no crash reporting services, no social media SDKs, and no tracking identifiers. It does not use the Advertising Identifier and does not track you across apps or websites.
7. Children's Privacy
The App is rated 13+ and is not directed to children under 13. Since we collect no data at all, we hold no personal information about anyone, including children.
8. Your Control and Your Rights
Because your data never leaves your device, you have complete control of it at all times:
- Delete an individual video, or a whole session, from your history inside the App.
- Delete every stored video at once from the storage section of your profile.
- Clear any profile field, including your photo, birth year, birthday, and country.
- Delete the App to remove everything it has stored.
There is no request to make of us, because there is nothing held by us to disclose, correct, or erase.
9. Data Retention
The App keeps what you record until you delete it or delete the App. We retain nothing, for any period.
10. Security
Your recordings are protected by your device's own security — your passcode, Face ID or Touch ID, and iOS app sandboxing. Keep your device updated and locked.
11. Backups
Reaction videos kept inside the App are excluded from iCloud device backup, because exports already go to your Photos library and video is large. Anything saved to Photos follows your own iCloud Photos settings.
12. International Users
No data is transferred anywhere, so no international data transfer takes place.
13. Future Features
We are considering an optional feature that would compare your answers with other players. It does not exist in the App today. If it is ever released it will be strictly opt-in, off by default, explained clearly before you turn it on, and this policy and the App Store privacy labels will be updated before any data is sent anywhere.
14. Changes to This Policy
If this policy changes, the effective date above changes with it, and material changes will be described in the App's release notes.
