A fax has to leave your phone to reach a fax machine, so this app cannot honestly claim it keeps everything local. This page says precisely what is sent, to whom, and how long it survives.
| Data | Why | How long |
|---|---|---|
| The fax number you enter | To dial the recipient, and to block abusive destinations | Kept with the transmission record |
| The text, documents and photos you send | They are the fax | Deleted from our servers after 30 days |
| Rendered page images | So you can see what was sent, in History | Deleted with the fax |
| Faxes received on your number | To show them to you | Until you delete them or release the number |
| A device identifier (Apple App Attest) | Proves requests come from a genuine copy of the app; this is what stops the service being used as an anonymous spam relay | While the app is installed |
| Subscription status | To unlock sending and number ownership | While the subscription exists |
| Crash reports | Diagnostics — the stack trace of a crash, the device model and the iOS version, so a bug can be found and fixed | Retained by Firebase Crashlytics for up to 90 days |
The app sends general installation, onboarding and subscription interactions to our first-party Attribution System. Google Firebase Analytics also receives app and device context, an analytics installation identifier, onboarding outcomes, and general fax-send attempt, acceptance or failure events. Acceptance means the service queued the request, not that the recipient received a fax. Firebase does not receive fax contents, page images, recipient phone numbers or text you enter through these product events. Events may appear as generic breadcrumbs in Crashlytics. The app does not request advertising-identifier access. See Firebase privacy information.
Faxing is a telephone service, and we do not own telephone lines. Transmissions are carried by Telnyx, a licensed communications provider, which dials the recipient and reports the outcome. The document is fetched by Telnyx over a signed, short-lived link and is not stored by them on our behalf. Their handling is governed by the Telnyx privacy policy.
Subscription purchases are processed by Apple. Entitlement state is managed through Adapty, which receives a purchase identifier and your subscription status — never the contents of a fax.
When the app crashes, a report is sent to Firebase Crashlytics (Google). It contains the stack trace, the device model, the iOS version and the same device identifier described above — never a fax, a page, a phone number you dialled, or anything you typed. Its handling is governed by the Firebase privacy documentation.
We do not sell personal data, and we do not share it for advertising or profiling.
Sent faxes, their pages and their delivery records are deleted 30 days after transmission. You can delete your data at any time from Profile → Delete my data, which removes every fax, page image and record tied to your device. Releasing a received number deletes the faxes stored under it.
Where the GDPR applies, we process your data to perform the service you asked for (Article 6(1)(b)) and, for abuse prevention, on our legitimate interest in keeping the service from being used for spam (Article 6(1)(f)). You may request access, correction, export or erasure by writing to the support address below. Because the app has no accounts, we identify your data by the device identifier the app sends — deleting the app without deleting your data first leaves us no way to tie a request to it.
The app is not directed at children and we do not knowingly process data from anyone under 13.
If this policy changes materially, the updated date above changes with it and the new version appears here before it takes effect.
