Fax Booth privacy

Last updated November 5, 2026. Fax Booth is made by Solomon Dev Studio LLC, 6701 Corporate Dr, Ste N, Johnston, IA 50131.

The short version

You don't need an account. Signing in with Google is optional. We keep your fax only as long as it takes to send it, then delete it. We don't sell your information, show ads, or use analytics.

What we handle when you send a fax

• The pages you add, and the fax we make from them.
• The fax number you're sending to, and anything you type for the cover page: names, your phone number, a note.
• An anonymous ID for this copy of the app, which holds your credits.
• The carrier's record of the call: time, pages sent and call length.

What we handle when you receive a fax

• The fax number you rent, and how many days and pages it has left.
• Each fax sent to it: the sender's fax number, the pages, and the time it arrived.

How long we keep it

• Pages, the fax file and the receipt are deleted within about 24 hours of the fax's final result.
• Names, your note and your phone number are deleted at the same time, and the number you faxed is masked to its last four digits.
• A fax you start and never send is deleted after 24 hours.
• Faxes you receive are deleted 7 days after your rented number ends.
• We keep the record of credits and purchases, and the carrier's delivery record, because they are the proof of what you paid for.

Who helps us run it

• Telnyx carries the fax over the phone network.
• Google Firebase runs our server and stores the fax until it is deleted.
• Google Play takes every payment. We never see your card, only a confirmation of the purchase.

On your phone

The camera is used only to scan pages you choose, and photos or PDFs are read only when you pick them. A list of your recent faxes stays on the phone. If you allow notifications, we store a push address (through Google Firebase Cloud Messaging) to tell you how a fax ended and when one arrives at your number. When you save a fax or a receipt, it goes to your phone's Downloads folder and stays there; we never see it.

Your recovery code

Your credits are tied to the app, not to you. The recovery code shown in the app moves them to a new phone. Anyone with that code can use your credits, so keep it private. Without it, we can't tell which credits are yours.

If you sign in with Google

Signing in is optional and only in Settings. If you do, Google Firebase Authentication gives us a sign-in ID for you and your email address. We store them with your app's ID so your credits, your fax number and your faxes follow you to another phone where you sign in. Signing in on a second phone moves that phone's credits onto your account. We never get your Google password, and we don't use your email for anything else.

To delete the account, open Settings, then Your account, then Delete account. We delete your sign-in ID and email straight away, from our records and from Firebase Authentication; your credits, number and faxes stay on the phone as they were before you signed in. You can also ask by email: see how to delete your Fax Booth account and data.

Your choices and requests

To ask us to delete what we hold, or with any question, email solomon@solomondevstudio.com and include your recovery code (or the email you signed in with) so we can find your records.

Not for children

Fax Booth is not directed at children under 13. If we learn a child has sent us personal information, we will delete it.

Changes

If this policy changes, we'll update this page and the date at the top.
