Support
Something not working, or a question about what eSign Me does with your documents? Write to support@esignby.app. One person reads that mailbox, and you will normally have an answer within two working days.
It gets faster if the first email already says: your iPhone model and iOS version, the app version (Settings, the line at the bottom of the screen), what you did, and what you expected to happen instead.
Common questions
Does the person I send a document to need the app? No. They open a link in their browser, sign there, and the signed PDF comes back to your library. No install, no account.
Which iPhones does the app run on? iPhone with iOS 18 or later.
How large a document can I send for signature? Up to 25 MB. Signing and exporting on your own device has no such limit.
How long does a signing link stay valid? 7 days from the moment you send it. After that the link stops working and the document is removed.
Where are my documents kept? Scanning, signing and exporting all happen on your iPhone — nothing is sent to us for that. A document is uploaded to our servers only when you send it to someone for signature, and only for as long as that request needs it. Your signature itself is never uploaded. The details, including the deletion schedule, are in the Privacy Policy.
Can you delete my data? Yes. Write to support@esignby.app and say what to delete. Because there are no accounts, we usually need something to find it by — the signing link, or the email address the invitation was sent to.
Sending a document for signature fails every time. Tell us what the screen says. That message distinguishes a network problem from a device the app cannot verify, and the two are fixed in different ways.
