Questions
- Can I cancel at any time?
- Yes, in the customer portal. Pro stays on until the end of the period you paid for.
- What if it doesn't work for me?
- Email us within 14 days of any charge and we refund it in full. See the refund policy.
- How do I reach you?
- Email a@pr.tools.
- Where is my data?
- In your browser. The extension keeps your settings and saved work in local extension storage; the only thing it sends out is your license key, to Polar, to check that Pro is active.
