Mardo support
The file stays yours.
So does the license.
For license help, email support@mardo.app from the delivery address. Include the Stripe receipt or order identifier when available and the bounded text from Mardo → Mardo License… → Copy Diagnostic. Do not send document contents, payment-card data, passwords, private keys, or unrelated system logs.
Install a license
Open Mardo License…, paste the complete 272-character certificate or choose the .flooflicense file, and confirm “Licensed to NAME — Mardo 1.” Verification is local and works offline.
Recover a purchase
Use the automatic recovery page with the Stripe Checkout Session ID and delivery email. It re-sends the exact original certificate; it does not generate another license.
Safe support
Floof Logic never asks for your full card number, document contents, account password, or the private signing key. A complete license certificate is usable and should be shared only through the private recovery and support channel.
