Talk to a human

CertAlert is built by one independent developer, not a support team. Email support@certalert.uk and you will get a reply from the person who actually writes the code, usually within one working day. Include your device (for example, iPhone 15 or Pixel 8) and what you were doing when the problem happened. Screenshots help a lot.

Reminders

Reminders are a Pro feature. Free shows the red / amber / green status when you open the app; Pro schedules notifications on your phone at 90, 60, 30, 7 and 0 days before each expiry, at a time you choose in Settings.

If reminders are not arriving:

Check CertAlert has notification permission in your phone’s Settings.
Make sure Pro is active (Settings shows your plan).
Open the app once after changing certificates so the schedule refreshes.

Reminders are scheduled locally, so they work without signal and never depend on our servers.

Backup is optional and Pro-only. When you turn it on, we email you a one-time sign-in link. If the email has not arrived within a couple of minutes, check spam or promotions folders for a message from login@certalert.uk, and check the address you typed.

To restore on a new phone: install CertAlert, upgrade or restore your Pro purchase, turn on cloud backup in Settings, and sign in with the same email.

Subscriptions and billing

Pro is billed by Apple or Google, not by us. To view, change or cancel:

iPhone or iPad — Manage subscriptions in your Apple account
Android — Manage subscriptions in Google Play

Restoring a purchase: in CertAlert go to Settings and tap Restore purchases while signed in to the same store account you bought with.

Refunds are handled by the store under their policies; we cannot issue them directly, but email us if something has gone wrong and we will help.

Proof packs

Open a property and choose Proof pack. Free shows a preview; Pro lets you share or save the PDF. The pack lists every certificate with issuer, reference, dates and evidence photos, plus whether it was served to the tenant.

Deleting your data

In the app, go to Settings → Delete account. That removes every property, certificate and evidence photo on this phone and, if you use cloud backup, the copy on our servers. A Pro subscription stays with Apple or Google until you cancel it in the store.

If you cannot open the app, email support@certalert.uk from the address you signed in with.

Report a security issue

If you believe you have found a vulnerability, please email support@certalert.uk with the details before disclosing it publicly. We will acknowledge within two working days.
