Support & contact — SIGNO

Version of November 5, 2026.

Contact

Email irek_karon@icloud.com. The link opens your mail app. This is the only SIGNO support address.

Please include your device model, iOS version, SIGNO version (Settings › Version) and a short description. Do not send documents with your customers' details unless they are needed to solve the problem.

SIGNO Premium

Your first finalized document is free. To create more, get SIGNO Premium — a one-time App Store purchase, no subscription (product ID: app.signo.premium.lifetime). Your documents, preview, copies, printing and export always stay available without a purchase.

Restoring a purchase

After reinstalling, or on another device with the same Apple Account, open Settings › Premium in SIGNO and tap “Restore purchase”.

Payments and refunds

Apple handles payments and refunds. You can request a refund at reportaproblem.apple.com.

Where are my documents?

Documents are stored only on this device and in its backup (iCloud or a computer) if you turn it on. Deleting the app without a backup deletes the documents, so send or save the PDFs you need first (Settings › Backup & export).

Checking a document

Every finalized document has an ID and a content fingerprint (SHA-256), shown in the PDF and in the document details in the app. The best confirmation is a PDF copy sent to the other party right after signing.

What a SIGNO document is

A SIGNO signature is a handwritten signature made with a finger or Apple Pencil on the screen. It is not a qualified electronic signature, and the document does not replace a tax receipt or an invoice.
