I really like this also reasonable priced.

Is there a way to export/download my saves in a reasonable way?

Thank you! Yes, you just get a zip file with all of your saved pages.

It looks like this:

├── files

│ └── 632daffb-2f4f-4795-bb4d-3149d24f4264

│ ├── original.html

│ ├── readerview.html

│ └── screenshot.png

├── manifest.json

└── metadata.csv
