Troubleshooting
Common problems and fixes
A PDF won't open
Make sure the file ends in .pdf and finished downloading completely. Password-protected or damaged files may not open. Try opening it from your phone's Files app, then update the app to the latest version.
My signature is in the wrong place
Before saving, tap the signature to select it, then drag it to the right spot and use the handles to resize it.
I can't find my file
Check the History list inside the app. Your files and History are stored only on your device, so they will not appear on another phone.
Sharing isn't working
Make sure the app you are sharing to is installed and up to date, and that you have enough free storage. If an email app rejects the file, try saving it first and attaching it from your files.
How do I restore my purchase?
Sign in with the same Google or Apple account you used to buy credits, then tap Restore purchases in the app.
The app isn't updating
Open the App Store or Google Play, search for the app and tap Update. Check that you are connected to the internet, have enough free storage and that your phone's operating system is supported.
How do I delete my account?
Open InkSeal, go to the Account tab, tap Delete account and confirm. It takes effect immediately. See the Delete account page for what is deleted and what is kept.
