Privacy policy
What stays on your iPhone
Everything you scan, photograph, say, type or ask is processed by the language model on your iPhone. None of it ever leaves the device: it is not sent to us or to anyone else. We do not use analytics or tracking, and there are no third-party analytics or advertising SDKs in the app.
Voice notes, their recordings, transcripts and summaries are made and kept on your iPhone. Speech is recognized by Apple's on-device speech recognition, never a server. Recordings made on Apple Watch go directly to your paired iPhone and are deleted from the watch once they arrive; they never pass through our servers. If you add a note's action items to Reminders, the app only creates those reminders and never reads your existing ones. The app works without an internet connection; the only optional exceptions are signing in for a friend pass and a one-time download of Apple's speech model for a language your iPhone does not have yet.
What we collect, and only if you sign in
You can use the whole app, including the trial and the purchase, without an account. Signing in is optional and exists only for the friend pass (a referral code). If you sign in with Apple, Google, Microsoft or an emailed code, we store:
- your name and email address;
- your phone number, only if you turn on "Contact me by phone" and enter one;
- your consent choices for marketing email and phone contact, with the time you made them and the version of the wording you saw;
- your personal referral code, which friend code you entered (if any), and who joined with your code;
- a random identifier for your iPhone, sent only when you redeem a friend code, so the same device cannot redeem twice;
- the Apple promo codes for the lifetime unlock that we assign to you as friend-pass rewards;
- if you sign in with Apple, the account identifier and token Apple gives us, so the sign-in can be revoked when you delete your account.
We do not collect your location, contacts, photos, voice recordings, questions or answers.
How we use it
- To run the friend pass: record who joined with your code, prevent the same person or device from redeeming twice, and send you an App Store promo code for the lifetime unlock when a new friend joins.
- To sign you in: send a one-time code to your email if you choose email sign-in.
- Only if you turned on "Email me tips and offers": occasional marketing email from SignalFree and CalMax Systems. Unsubscribe any time in the app or by replying to any email.
- Only if you turned on "Contact me by phone": calls, including automated calls, from SignalFree and CalMax Systems about updates and offers. You can withdraw this in the app at any time.
Both marketing choices are off unless you turn them on. We do not sell or rent personal data, and we do not use it for advertising.
Service providers
We share account data only with the providers that run the service for us, and only for that purpose:
- Cloudflare hosts our website, the friend-pass service and its database. It processes your IP address in transit to deliver requests; we do not store IP addresses.
- SMTP2GO sends sign-in codes and, if you agreed, our emails.
- Apple, Google or Microsoft: only the one you choose to sign in with. It confirms your identity and shares your name and email with us under its own privacy policy.
Purchases
The one-time unlock is sold and processed by Apple through the App Store. We never see your payment details.
How long we keep it
Account data is kept until you delete your account. When you do, we delete your name, email address, phone number, consent choices and Sign in with Apple tokens (and ask Apple to revoke them), sign you out everywhere, and anonymise the account. We keep the anonymised referral and redemption records (the referral code, the device identifier and any promo-code assignment) for up to 24 months to prevent fraud, such as the same device redeeming a friend code again. They are not linked to your name, email or phone.
Deleting your account
In the app, go to Settings → Account → Delete my account. It takes effect immediately. Your access on your iPhone, including a purchase, is not affected. You can also email hello@signalfree.app from the address on the account and we will delete it for you.
Where data is stored
Account data is stored with Cloudflare, encrypted in transit and at rest.
Children
SignalFree AI is not directed to children under 13, and we do not knowingly collect their information. If you believe a child has signed in, email us and we will delete the account.
Changes
If this policy changes in a way that matters, we will update the date above and the app will ask you to look at it again before anything new applies.
