Privacy Policy

SEYFR is a peer-to-peer file-transfer application built for direct peer-to-peer file transfer. This Privacy Policy explains our data practices when you install and use the SEYFR mobile and desktop applications.

1. Data Collection & Storage

SEYFR uses peer-to-peer networking to connect devices:

• No SEYFR File Storage: JITPOMI does not provide cloud storage for transferred files. SEYFR connects the devices directly when possible. Otherwise, a relay forwards the live, end-to-end encrypted transfer. SEYFR does not create a hosted copy that can be downloaded later.
• Local Storage: Received files are saved on the receiving device using the location or save options permitted by that platform. The sender also imports selected content into its local Iroh blob store so it can serve the live transfer.
• No Account Required: SEYFR does not require you to sign up. We don't ask for your name, email, phone number, or password.

2. Network & Connections

To link your devices, SEYFR uses QR codes, transfer tokens, or devices you choose to save:

• Encryption: File content is end-to-end encrypted in transit, whether the connection is direct or uses the relay fallback.
• Relay Infrastructure: Relays help devices exchange network information and establish a direct path. Once that path works, the relay steps back. If a direct path cannot be established, the relay forwards the live transfer while its contents remain end-to-end encrypted. It does not turn the transfer into a hosted file available for later download, but its operator can still observe connection metadata such as IP addresses, connection times, and the amount of relayed data.
• Direct Connections: When devices connect directly, the peers exchange network-address information, including IP addresses, as part of making the connection.
• Transfer Tickets: The QR code or ticket contains the sender's Iroh endpoint address, a 32-byte BLAKE3 root hash that identifies the selected transfer, and the blob format. The hash is an identifier and integrity fingerprint—not file data. The ticket contains no file bytes or file metadata. Think of it as a map plus a fingerprint, not the package. Treat it as sensitive and share it only with the intended receiver. It can be reused while the sender remains reachable and the content remains available.

Saved devices and discovery

When you save a device, SEYFR keeps its public device identity, display name, and pairing state locally. SEYFR uses local-network discovery and public Mainline DHT infrastructure to help saved devices find each other. Address records published to the DHT are encrypted for the intended paired device; transferred files, filenames, and approval messages are not published to the DHT.

Encryption does not hide all discovery metadata. Public records include a signing public key, sequence number, signature, and recipient-derived salt. DHT participants and network operators may observe IP addresses, timing, and lookup or publication activity. Saved-device discovery is not anonymous, and forgetting a device cannot immediately erase copies already held by public DHT nodes.

Retention and deletion

Saved-device records and received-file history remain on your device until removed through SEYFR or by clearing its application data. Forgetting a device revokes its saved-device access locally; it does not delete files either person has already received. Turning off received-file history does not delete the received files. Delete those files using SEYFR's file actions, where available, or your device's file manager.

SEYFR temporarily imports outgoing content into its local transfer store. Unreferenced content is eligible for automatic cleanup; stopping a transfer is not a promise of immediate secure erasure. App data and protected device keys follow each operating system's storage and removal behavior; uninstalling the app may leave exported files and platform-protected credentials behind.

3. Device Permissions

• Camera Access: We only ask for camera access so you can scan QR codes to connect your devices. SEYFR never uploads or shares your camera feeds.
• Storage Access: We only ask to access your files so we can send the ones you choose and save the ones you receive.
• Notifications: With your permission, SEYFR can notify you when an incoming saved-device transfer needs approval. Notifications may show the sending device's name. Sound, lock-screen visibility, and delivery are controlled by your operating system's settings. This does not enable background delivery on platforms that suspend SEYFR.

4. Third-Party Services

SEYFR includes optional public donation/monetization instructions for supporting development (via Mercury Bank and Venmo). We do not collect banking details, credit card numbers, or transactional analytics from your donations.

The public SEYFR website uses Google Analytics to measure visits and store-link clicks. This website measurement is separate from file-transfer content and is governed by Google's terms and privacy practices.

With website analytics consent, campaign link tags may be kept in this browser tab's session storage to preserve attribution when you open another SEYFR page. They expire after 30 minutes without a page-navigation refresh and are removed when analytics consent is withdrawn. This handoff does not create a visitor identifier or record file-transfer activity.

Apple, Google, and Microsoft may provide JITPOMI with aggregate store analytics such as listing views, downloads, installations, crashes, and broad usage or performance information under their own platform terms. These store reports are supplied by the platform; SEYFR does not include an in-app behavioral analytics SDK that records how you use the transfer interface.

The Android app may read Google Play's install-referrer data once after installation to determine which SEYFR campaign link led to the install. SEYFR records the matching campaign, Play-provided click and install times, and installed app version. This measurement does not include an advertising identifier, account identity, file names, file contents, or transfer activity.
