THE SMALL PRINT, IN PLAIN WORDS

A few good questions.

How do the two credit balances work?

Verified signup gives you 20 bonus credits once. They never expire and work on Free. Personal adds 50 monthly credits. Monthly credits are used first; any unused monthly credits expire at renewal. Your bonus balance stays intact. A successful generation costs 5 credits.

When do my monthly credits refresh?

Your first Personal activation starts your monthly cycle. Credits refresh to 50 on the same date each month (UTC); for shorter months, on the last day. Unused credits and missed months do not accumulate. Your next renewal date is shown in your account.

What happens if I switch to Free?

You review and confirm the change first. Personal stays active until the end of your current cycle, then you move to Free and unused monthly credits expire. Bonus credits and diagrams stay. You can cancel the switch before that date. Switching back does not create a second allowance for the same cycle.

When is the first charge?

The first calendar month is free once. Checkout shows the exact first charge date, then $3.50/month including tax. Cancel in the billing portal before that date to avoid a charge. Existing beta accounts are never charged without a separate checkout.

What about credits I already received?

They stay in your bonus balance. The new 20-credit signup offer applies to new grants; it does not reduce credits already issued or give existing accounts a second welcome bonus.

Data, provider and retention

We collect allowlisted editor, sign-in, plan and AI interactions; fixed page categories; page duration; and only utm_source, utm_medium and utm_campaign labels restricted to 64 letters, digits, hyphens or underscores. Do not put personal data in campaign labels. We discard full URLs, other query parameters, referrers, advertising click IDs, original IP addresses and user agents. After consent, this tab stores a random visit identifier and the first valid campaign labels in sessionStorage. A visit expires after 30 minutes without a tracked event or 24 hours at most. Events pass through our server to PostHog EU under a random identifier separate from your account, with a minimal technical profile for deletion. No account linking, device fingerprinting, automatic click collection or session replay. Your choice lasts 180 days on this browser and origin. Withdrawal immediately stops new events, clears visit/campaign storage and requests deletion of linked history; queued is not confirmed erasure. Necessary sign-in and local diagrams continue to work. Earlier identifiers may remain only to complete deletion.

Privacy policy

Your choice lasts 180 days in this browser. You can change it in Cookies & privacy.

Turning analytics off immediately stops new events and requests deletion of linked history. Your diagrams are kept.
