Privacy and support
Summoner collects no data. It opens files already on your iPhone or iPad, has no server, no account and no analytics, and makes no network requests of its own.
The files you open
When you open a file from Files or share one to Summoner, the app reads it on your device and shows it. Summoner uploads nothing and sends your file nowhere.
A file's own code can make requests of its own. If an HTML file loads a library or a font from the web, your device fetches it the way any web page would. Those requests come from the file, not from Summoner, and they only happen if the file was written to make them.
Links
Tap a link to another site inside a file and it opens outside Summoner, in Safari or whichever app you use for links. Summoner stays on your file.
What Summoner remembers
Recents keeps the last 15 files you opened, so you can get back to them. For each one it stores the file's name, its type, when you opened it and a pointer iOS uses to find the file again. The pointer is not a copy of the file. All of it stays on your device.
A file can save its own data too, like a to-do list's items, and libraries it loads from the web are cached. That also stays on your device.
Swipe a file in Recents to remove it. Deleting the app removes everything it kept.
Permissions
None. Summoner doesn't ask for your photos, contacts, location, camera or microphone, and it doesn't track you across apps.
Crash reports
If you've chosen to share analytics with app developers in Settings, Apple may pass me anonymous crash reports. That is Apple's system and your choice. Summoner adds nothing to it.

Support
Found a file that won't open, or a bug, or a question this page doesn't answer? Write to summoner@rexchekal.com. It reaches me, Rex Chekal, the person who made Summoner.
It helps to attach the file, if you can share it, and say where it came from.
