Frequently Asked Questions

RedactProof processes documents in your browser using client-side technology. Your files are never uploaded. Precision Engine sends extracted text (not files) to Cloudflare for enhanced detection. This text is used for inference only - not stored as document content, not used for training. Need everything to stay on-device? Use the standard engine - no data leaves your browser.

Your documents stay on your device - they exist in browser memory during processing and are not persisted. If you enable Precision Engine (a Pro feature), extracted text is routed through Cloudflare Workers AI over an encrypted connection for enhanced detection. This text is used for inference only - not stored as document content, not used for model training. Your actual files are never sent. Need everything to stay on-device? Use the standard engine - no data leaves your browser. We store your account details, usage stats, and cryptographic hashes for verification certificates. We do not store document content.

For Core tier billing, we need to count unique documents without knowing what those documents are. We use a privacy-preserving technique: your browser creates a one-way code from your document that changes each month. We can count these codes to track usage, but we cannot reverse them to identify your documents. Even if someone had your original document, they couldn't prove you processed it.

RedactProof is designed to support data privacy compliance. Documents stay on your device, giving you full control over personal data processing, which aligns with data privacy requirements for data minimization and security. Precision Engine processes extracted text via Cloudflare for inference only - not stored as document content, not used for training. Need everything to stay on-device? Use the standard engine.

Our AI model detects over 60 types of sensitive information including names, addresses, phone numbers, email addresses, social security numbers, bank account details, medical record numbers, crypto wallet addresses, developer secrets, and more.

Yes. You can use AI detection to find PII automatically, then review and adjust before applying redactions. You can also draw manual redaction boxes on any part of the document.

Verification certificates are cryptographically signed records that confirm a document was redacted at a specific time. They include cryptographic hashes that link the redacted document to its source, without revealing original content. Any modification to the certificate - even changing one character - is immediately detectable. Verification can be performed at redactproof.com/verify or using our independent verifier on GitHub.

Yes - a free trial on one document. Sign up and redact one source document with the full Pro feature set, with unlimited attempts and re-exports of that document and no card required. If you only need a handful of documents, Flex Packs start at $25 for five; the Core individual licence is $249/year.

Core is an individual annual licence: on-device AI detection, professional exports, image redaction and OCR text restoration - everything one person needs to redact privately. Pro adds the proof layer - tamper-evident certificates and the full audit trail (per-redaction log, certificate history, settings history) - plus the Precision detection engine, bulk processing, session checkpoints, the exclusion list, exemption codes, legal discovery export with Bates numbering, priority email support, and team administration from 2 seats. Both include secure pixel-burn redaction.

We accept all major credit cards through Stripe. Enterprise customers can arrange invoice billing with dedicated account management, regional data residency, and tailored Data Processing Agreements. Contact hello@redactproof.com for details.

Yes. You can cancel your subscription at any time. You'll continue to have access until the end of your billing period.

If a payment fails, you have a 3-day grace period with full access while we retry the payment. After 3 days, your account becomes view-only: you can still log in and see your audit history and certificates, but redaction and export need an active plan. Update your payment method anytime to restore full access immediately.

Pro is priced per seat with volume tiers - $99/seat/mo for 1-2 seats, $87 from 3 seats, stepping down to $69/seat/mo at 50+. Team administration features unlock from 2 seats. You can run 1 to 100 seats and adjust at any time from your account settings.

RedactProof works in all modern browsers including Chrome, Firefox, Safari, and Edge. We recommend using the latest version for the best experience.

All plans support PDF documents, including scanned PDFs. Paid plans (Core and above) also support image files (JPG, PNG, TIFF, WebP, HEIC, BMP) - these are converted to PDF and OCR'd automatically in your browser. Need to redact a different format? Convert it to PDF first.

There's no hard limit, but very large files may be slower to process as everything happens in your browser. For best performance, we recommend files under 50MB.

RedactProof is designed to support CCPA and HIPAA-aligned workflows. Documents are processed on your device - no PHI or personal data is uploaded to our servers during standard redaction. Precision Engine (Pro) sends extracted text to Cloudflare for inference only - not stored, not used for training. Need full on-device processing? Use the standard engine.

Yes. Enterprise customers handling PHI can request a Business Associate Agreement. Contact hello@redactproof.com with your requirements.

Yes - FOIA responses and legal disclosures are a core use case. RedactProof lets you redact sensitive information before disclosure, apply redactions to scanned documents, and export with tamper-evident certificates that provide an auditable record of what was redacted and when.
