What counts as a slot?
A slot means one browser profile, not a physical machine. Chrome and Safari on one computer use two slots; multiple tabs in the same profile use one. Clearing site data may require reactivation and replacing an old binding.

Subscription details stay separate from your documents.
The subscription does not change local document processing. Billing will use your email, payment status and browser bindings—not your PDF content. Ad-free does not mean analytics-free; privacy and cookie choices still apply.
No. The free PDF tools remain available. A subscription is for removing website ads on activated browsers, not for unlocking PDF features.
Basic includes one slot. Premium offers 2–20 slots. Both provide the same ad-free benefit; the number of slots is the difference.
Your paid subscription remains on the server. The browser may lose its activation credential. Enter your code again, and verify your purchase email to remove an old binding if all slots are occupied.
The planned reset flow requires purchase-email verification. A reset replaces the code, invalidates the old one and clears all browser bindings. The paid-through date stays the same.
Enter your code and verify your purchase email to stop automatic renewal. Ad-free access continues to the end of the paid period. Cancelling renewal is separate from requesting a refund.
When payments are configured, you can check out securely with Stripe. Your code and access are issued only after payment is confirmed. If payments are not configured here yet, checkout stays disabled.
