Overview
Cassette is a local audio and video player for iOS. All media files you add are stored exclusively on your device — Cassette has no servers, no user accounts, and does not transmit your personal files or library data to any third party.
Cassette displays advertising via Google AdMob to support the free availability of the app. AdMob may collect certain device identifiers and usage data as described in this policy.

Advertising — Google AdMob
Cassette uses Google AdMob to display advertisements. AdMob is operated by Google LLC, 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA.
Types of ads displayed:
- App Open ads (shown when the app launches)
- Interstitial ads (shown between navigation actions)
- Native ads (displayed inline in the library list)
Data AdMob may collect:
- Advertising identifier (IDFA) — only if you grant tracking permission
- Anonymized device identifiers
- App usage and interaction data (ad impressions, clicks)
- Approximate location derived from IP address
- Device model, OS version, language, and time zone
Google uses this data to deliver and measure advertisements. For full details, see Google's Privacy Policy and How Google uses data when you use partners' apps.
App Tracking Transparency (ATT)
On iOS 14.5 and later, Cassette may request your permission to access the Advertising Identifier (IDFA) through Apple's App Tracking Transparency framework.
- If you allow tracking: AdMob may use your IDFA to deliver personalized ads and measure ad effectiveness across apps.
- If you deny tracking: Your IDFA is not accessed. AdMob will serve non-personalized, contextual ads only.
You can change your decision at any time in Settings → Privacy & Security → Tracking.
GDPR — European Users (EEA/UK)
If you are located in the European Economic Area (EEA) or the United Kingdom, the General Data Protection Regulation (GDPR) and UK GDPR apply to the processing of your personal data.
At first launch, Cassette displays a Google-powered consent form (User Messaging Platform) that allows you to choose whether advertising data is processed for personalized purposes.
Your rights under GDPR:
- Right of access — Request a copy of data held about you.
- Right to rectification — Request correction of inaccurate data.
- Right to erasure — Request deletion of your data ("right to be forgotten").
- Right to restriction — Request limited processing of your data.
- Right to data portability — Receive your data in a structured format.
- Right to object — Object to processing based on legitimate interests.
- Right to withdraw consent — Withdraw advertising consent when the in-app consent form is presented (EU/EEA), or contact us at mohcinebadour@gmail.com.
Because Cassette itself stores no personal data on any server, the data subject rights above primarily relate to data held by Google AdMob. To exercise rights with respect to Google's data, please use Google's Privacy Dashboard or contact Google directly.
For any privacy request related to Cassette specifically, contact us at the address below. We will respond within 30 days.
California Residents (CCPA/CPRA)
Under the California Consumer Privacy Act (CCPA) and California Privacy Rights Act (CPRA), California residents have specific rights regarding their personal information.
Because Cassette does not sell personal information and does not collect personal data beyond what AdMob processes for advertising, most CCPA provisions are satisfied by the ATT framework already in place. California residents may contact us to request information about data practices or to opt out of any future data sale.
iOS Permissions Requested
| Permission | Purpose | Required |

All permissions are requested only at the moment they are needed (just-in-time), never at launch. Denying any permission does not affect core playback functionality.
Data Retention & Deletion
All data stored by Cassette (library index, playback positions, media files) resides exclusively on your device in the app's private container. You can delete this data at any time by:
- Deleting individual files within the app
- Uninstalling Cassette from your device (removes all app data permanently)
Data collected by Google AdMob is governed by Google's data retention policies.
