Private Chat and image review

Video compression, audio extraction, photo compression, Album Cleaner and Private Vault media processing run locally, without cloud compression. Local tools do not require a chat account. Private Chat uses a separate identity: text messages use OpenMLS end-to-end encryption; recipient images use AES-GCM attachment ciphertext and MLS metadata ciphertext. Each chat image also has a separate moderation copy decryptable by an isolated review service. Authorized reviewers can inspect individual cases, with access and actions recorded in an audit trail. This moderation copy is not end-to-end encrypted solely between the communicating users.

The edge gateway uses the connection IP only for per-IP request rate limiting, concurrent-connection security controls and abuse prevention. The corresponding rate-limit state is held in Nginx shared memory: connection counts are released when the request or connection ends, request-rate states are evicted on a least-recently-used basis when the zone needs to reclaim capacity, and in-memory state disappears when the Nginx instance stops. Chat routes disable access logs and remove standard IP-forwarding headers before proxying to the chat service; the chat database and chat-service logs do not store the connection IP. Other Nginx or host error/security logs may still record it. Their actual fields and retention have not been verified and remain a separate gate before chat-image sending can be enabled; the disclosure must then be updated to match the evidence. The connection IP is not used for advertising tracking. Chat servers process numeric user IDs, public keys, the contact graph, message senders and recipients, routing and delivery times, image dimensions and digests, moderation cases, bans, authentication and security audit metadata for communication and content safety. Recipient image ciphertext is cleared after download acknowledgement or seven days. Pending, rejected or failed review copies are retained for a configured period of up to thirty days. Approved review copies are removed in the decision transaction unless held. A legal hold overrides these periods until authorized release. Case and audit metadata are retained separately and are not automatically removed by image cleanup.

Provider copy deletion is attempted through durable jobs and can fail or be unsupported; database content deletion does not prove backup erasure. Local history and the system Recently Deleted area have separate lifetimes. New chat-image sending is currently unavailable. Before activation, we will identify the actual review provider, purposes, regions, retention and deletion rules and obtain the required explicit permission before sharing. Text does not enter image review. These data are not used for advertising tracking. Effective Date: September 10, 2026.

2. App Features

Aiwei Video Compressor is a local video compression tool. The first version mainly provides:

  1. Choosing videos from the system media library.
  2. Setting compression mode and compression ratio.
  3. Compressing videos locally on the device.
  4. Previewing video results.
  5. Saving compressed videos to the system media library.
  6. Sharing videos through the system share sheet.
  7. Sending issue feedback through email or system sharing.

Local tools do not require a chat account, upload user videos, or provide cloud video compression.

3. Frequently Asked Questions

Why does the app need video permission?

Video read access is used to choose videos for compression. Media library write access is used to save compressed videos to the system media library. You can manage these permissions in iOS or Android system settings.

Will my videos be uploaded?

No. Video compression, preview, and saving are performed locally on your device by default. Selected actual video files are not uploaded.

Why can some videos not be compressed?

Videos can differ by format, codec, resolution, HDR status, file integrity, and system compatibility. If a video cannot be compressed, try another video or send us the issue screenshot, video format, and system version by email.

Why does quality change after compression?

Video compression trades file size for image quality. Higher compression usually creates smaller files, but may reduce quality more noticeably. Choose the compression mode based on your use case.

What should I do if saving fails?

Please make sure the app has permission to save to the system media library and check that your device has enough storage. If the issue continues, restart the app or device and try again.

What should I do if sharing fails?

Sharing is handled by the system share sheet and the third-party app you choose. If sharing fails, make sure the target app is available, or save the video first and then share it from the media library.
