Limits
Free: 30 readings. Maximum 256 KiB per saved article including notes and 100 MiB for the serialized dataset. Browser disk quota may impose a lower limit. Text only: images, original formatting, interactive widgets and remote resources are omitted. PDFs, restricted Chrome pages, protected content and paywall bypass are unsupported. A saved snapshot does not change when its source changes; a different snapshot is a new version.
Backups
Merge validates the complete file and rejects conflicting IDs. Replacement requires a downloaded recovery copy, confirmation that you saved it, and a final confirmation. Existing data remains intact when validation or the transaction fails. Restored data above the Free count stays readable and exportable.
