Paperwind privacy policy

Last updated 4 November 2026.

Paperwind is provided by Kitewind Works, under the applicable data-protection law. See also our general privacy policy.

What we collect

• Account: your name, email and your firm's name.
• Documents: photos of invoices, receipts and similar pages that you capture, and the figures read from them. These can contain names and details of your clients and their suppliers; your firm decides what to upload.
• Questions: the typed questions you ask about your documents.
• Technical: app version and device type, to fix problems.

Why

To read, store, check and export your documents, and to run your account. We do not sell data and do not use it for advertising.

Who receives it

• Our servers (DigitalOcean) store your data.
• Anthropic, an AI provider, receives the text of a typed question and the document text needed to answer it, only when you ask one.
• Our payment partner receives billing details, never your documents.

How long

Documents are kept for five years, the usual retention period for accounting records, or until your firm deletes them. After a plan ends, data is read-only for 60 days and deleted at day 90.

Camera permission

The app asks for the camera only to photograph pages. Photos are uploaded to your firm's account.

Your rights and deletion

Ask to access, correct, export or delete your data by emailing contact@kitewindworks.com, or follow Delete your account.
