Who we are. docuProof™ is operated by BuyWayz LLC, a Wyoming company, doing business as docuProof.io (“docuProof,” “we,” “us,” or “our”).

What we do. We provide a non-custodial proof-of-existence service. You compute a cryptographic fingerprint (SHA-256 hash) of your file locally in your browser; we anchor that hash and return a permanent verification link. We are not a notary or a legal certification service.

1) Data we do not collect

• No file contents. Your document never leaves your device. We do not upload, scan, or store your files.
• No third-party ad pixels. We don’t run invasive tracking beacons.

2) Data we process to deliver the service

• Document hash (SHA-256): submitted by you to create a proof record. This is a one-way fingerprint and cannot reconstruct your file.
• Basic proof metadata: proof ID, timestamps, optional filename/display name you provide, and a public verification URL.
• Payment data via Stripe: We use Stripe for one-time purchases and subscriptions. Stripe is a separate controller for payment data; we don’t store full card numbers. See stripe.com/privacy.
• Operational logs: limited, short-lived logs for security and uptime (e.g., function invocation, error traces). No file contents.

2a) Email delivery

We use an email service provider (such as Postmark) to send transactional messages including receipts, proof delivery notices, and verification links. This involves processing your email address, the message body, and minimal delivery metadata such as timestamps and message IDs. During Postmark domain approval, delivery may be limited to addresses under the same verified domain.

3) Public nature of proofs

When you create a proof, the verification page URL and proof fields you provide (e.g., display name) may be publicly accessible by anyone with the link. Do not include confidential or personal data in fields you intend to make public.

4) Legal bases & purposes

• Contract: to provide the timestamping and verification service you request.
• Legitimate interests: to secure, maintain, and improve the service; to prevent abuse and fraud.
• Compliance: to meet obligations under applicable law (e.g., tax/financial record retention related to payments).

5) Retention

• Proof records: retained to preserve verifiability of your proofs.
• Payment records: retained per legal/tax requirements.
• Operational logs: retained for a limited time and rotated.

6) Your choices

• Minimize inputs: Provide only what you want to appear on a public proof page.
• Questions: Contact support@docuproof.io.

7) Children’s privacy

docuProof is not intended for children under 16. If you believe a minor has submitted personal data, contact us and we will address it promptly.

8) International users

We operate from the United States (Wyoming). By using docuProof, you understand your data may be processed in the U.S. We apply the practices described here regardless of your location.

9) Security

We apply industry-standard controls to our systems and never ingest your file contents. No online service can guarantee perfect security; please use strong device security and avoid embedding sensitive information in public proof fields.

10) Changes

We may update this policy as our service evolves. Material changes will be posted here with a new “Effective” date. Continued use constitutes acceptance of the revised policy.
