upgrade.tools is a small, independent project — and feedback from users is the main way pricing data stays accurate. Every message is read.
For partnerships, see the dedicated address below.
Subscription prices change often and vary by country. If a calculator shows something different from what the service officially charges, we want to know. Including these details makes corrections much faster:
Is there a subscription you'd like to see analyzed? Tell us the service name and the country you'd use it in. Requests with the most demand get built first — check the homepage to see what's live and what's coming soon.
For partnership or business inquiries, email partnerships@upgrade.tools. For everything else — corrections, data questions, feedback on how calculations work — use feedback@upgrade.tools. You can also read how pricing is sourced and verified.
We're an independent project, not a support desk — we can't promise a fixed response time. Verified price corrections are applied to calculator data, and each calculator shows when its data was last checked. If your report leads to a fix, thank you: that's the community keeping this resource honest.
