Before you buy.
- What stays free?
- 1 profile with 5 request headers, wildcard URL filters, tab-only rules, and ModHeader import and export. Free forever.
- Does Pro send anything about my browsing?
- No. Pro checks your licence once a day: your licence key and a random install id go to our licence server. Nothing about the sites you visit or the headers you set.
- Can I cancel the monthly plan?
- Yes, any time, from the link in your receipt email or from the Manage plan page. Pro keeps working until the end of the month you paid for.
- What if it isn’t for me?
- Email [email protected] within 7 days of paying and we’ll refund you.
- How many browsers can I use it on?
- One licence key works in one browser at a time. You can move it to another browser whenever you like.
- Who handles the payment?
- Freemius, our payment processor and merchant of record. They handle your card details and send the receipt; we never see your card.
