Frequently Asked Questions
What's the difference between Free and Paid tiers?
The Free tier gives you unlimited access to our CLI and Web UI for local hashing. Paid tiers add cloud storage, blockchain timestamping, and proof history tracking.
What is "Founding Member" pricing?
The first 100 users who subscribe get €5/month pricing locked in forever. Even as we add features and raise prices, Founding Members keep their €5 rate for life.
Are there usage limits?
Pro tier includes unlimited cloud storage with fair use (~100 proofs/month is typical). Need more? Email us - we're flexible for genuine use cases.
Do you store my files?
No. We only store cryptographic hashes (SHA-256) of your files, never the files themselves. Your files stay on your machine.
Can I cancel anytime?
Yes. Cancel your subscription anytime from your account dashboard. You'll still have access until the end of your billing period.
