Important info for Safari
Safari 13.1+ on macOS, as well as Safari on iOS/iPadOS 13.4+, introduced a seven-day cap on all locally-stored data by websites. This means that unless you open PhotoStack at least once a week, your saved watermarks could be deleted.
The only way to avoid losing your watermarks is to export them as files (from the watermark list), then re-import them after Safari wipes PhotoStack's data.
In addition, PhotoStack may not be able to download files (completed images, exported watermarks, etc.) when it is opened from the iOS home screen. To get around this, open edit.photostack.app in your browser instead.
Select photos from your computer or the web to get started.
Supported file types: ZIP, MS Office (DOCX, PPTX, XLSX)

Some browsers throttle background windows and tabs. To speed up exports, don't minimize PhotoStack or switch to another tab/window.
Downloading individual files doesn't work correctly in some browsers. If you experience problems, use one of the other options.

Watermarks stored in your browserdevice are displayed here. You can transfer them to other devices or browsers by exporting the watermarks to a file and importing them on another device/browser.
PhotoStack 2 cannot automatically access watermarks created in earlier versions. If you want to import your old watermarks, see this help page.
