Using QuillSign
QuillSign lets you place visible image or text marks on copies of PDFs. You may use only marks that you own or are authorized to apply. You are responsible for checking every output and deciding whether it is suitable for your purpose.
What the mark means
QuillSign does not create a cryptographic digital signature, certificate, audit trail, timestamp, identity check, or proof of intent. It does not decide whether a mark is legally sufficient. Get qualified advice when a document has formal signing requirements.
Documents we do not change
Encrypted, permission-restricted, certified, already signed, damaged, and unsupported PDFs may be rejected. QuillSign does not remove passwords or bypass document permissions. Original files are not overwritten.
Browser storage
Active PDFs, previews, marks, and exports are temporary in the browser tab. Pro recipes and mark assets are saved only after you ask, in browser storage separated by verified user ID on that device. You can delete them from the tool. They are not cloud backups.
Paid plans
$3/month for this app (cancel anytime), or $15/month for Crate Pass (all apps). Subscriptions renew monthly until cancelled. Paid access depends on the shared Cashew Crate account and entitlement service. Features may be adjusted to protect browser stability and document safety.
Refund help
Email [email protected] with your order number and a description of the issue.
Availability and liability
QuillSign is provided without a promise that every PDF will be supported or that every output will meet a legal, contractual, or filing requirement. Keep your source files and inspect all completed copies before use.
