Summary
Audio import, preview, trimming, join review, rendering, and validation happen on your iPhone or iPad.
MemoJoin does not require an account and does not include advertising, tracking, a custom analytics service, or a developer backend for audio processing. This policy covers the MemoJoin app, its Action Extension, this website, and support messages you choose to send.
Data handled by the app
Recordings and working copies
When you choose audio through Files or share compatible audio to MemoJoin, the app creates local working copies so the project does not depend on continued access to the source. MemoJoin reads technical details needed to work with the file, such as duration, file size, audio format, sample rate, channel count, and a local checksum used to detect duplicates and verify a shared copy.
Recording files, filenames, project names, clip names, trim ranges, order, gap settings, and export metadata stay in the app container or its App Group container. MemoJoin does not send this information to MemoJoin servers.
Permissions
MemoJoin uses system file and sharing interfaces only when you choose an import, save, or share action. The launch version does not request microphone, Photos, location, contacts, or tracking permission.
Completed exports
Validated M4A results are stored locally in read-only Merge History until you delete an item or clear the history. Editing, replacing, or clearing the Current Merge does not delete completed results.
Apple, hosting, and support services
Apple platform services
The App Store processes the purchase and may provide developers with aggregated product-page, sales, refund, and crash information. Depending on your device settings, Apple may make crash or diagnostic reports available to the developer. MemoJoin does not add a third-party crash-reporting or analytics SDK.
This website
This website is a static site and does not use an account, analytics script, advertising pixel, contact form, or cookie-based tracking. Cloudflare delivers and protects the site and may process standard request information, such as IP address, user agent, requested URL, timing, and security signals, under the Cloudflare Privacy Policy.
Support email
If you email support, we receive the address, message, and any files you choose to attach. We use that information to respond, diagnose the issue, prevent abuse, and maintain a support record. Do not attach private audio unless it is necessary, you choose to do so, and you have permission to share it.
Retention and deletion
- The Current Merge and its working copies remain until you replace or clear that merge.
- Completed results remain in Merge History until you delete an item or clear the history.
- Incomplete shared-import copies are cleaned after 24 hours. Ready shared imports are not silently deleted after seven days; the app reminds you to review them.
- Temporary files from cancelled, failed, or interrupted exports are cleaned and are not presented as completed results.
- Deleting the app normally removes data in its app containers. Copies saved to Files, shared to another app, or retained by an operating-system backup are controlled by those locations and services.
MemoJoin provides controls to clear the Current Merge, pending imports, individual completed results, or all Merge History. These actions do not modify the original recordings.
Children and lawful use
MemoJoin is a general-purpose utility and is not designed to collect personal information from children. Users are responsible for having the right to process and share the recordings they select, including recordings containing another person’s voice.
Policy changes and contact
We may update this policy if MemoJoin’s features, platform requirements, or data practices change. The effective date above will change when a material update is published.
