What FlatWaiver is
FlatWaiver is a web service for activity businesses that collect and manage digital liability waivers. An existing PDF can be uploaded and converted by AI into a signable form, with the original wording available for owner review before publication. Businesses can distribute signing links, print QR codes, or provide kiosk mode on a front-desk tablet. Visitors sign on phones without installing an app or creating accounts. For participants under 18, the process records a guardian’s name, relationship, and separate signature. Each signed waiver carries a timestamp, IP address, consent record, and SHA-256 hash, tied to the signed version. Records can be exported as CSV and signed PDFs downloaded even after cancellation. FlatWaiver says data is encrypted in transit and at rest, records are isolated with database-level row-level security, and signed records are append-only. The Everything, unlimited plan is $19 a month, with unlimited waivers, templates, and storage under fair-use terms. A 14-day trial is available; there is no free plan.

Who it suits
