Frequently asked
Will my data leave my machine? +
No. Tvastar runs entirely on your computer — no cloud, no telemetry, no analytics. License validation is the only outbound network call, and only the license key is sent.
How many devices can I use one license on? +
Three. You can deactivate a device from the customer portal to free up a slot at any time.
What's included with Perpetual? +
A one-time payment, Pro access forever on the version you bought, plus 12 months of free updates from the date of purchase. After that, your license keeps working on the version you have; new major versions are a discounted re-purchase.
Can I switch between Monthly and Yearly? +
Yes. The customer portal lets you upgrade or downgrade — proration is handled automatically.
Do you offer refunds? +
Yes. Polar processes refunds within 14 days of purchase, no questions asked.
How does the Free tier compare? +
Tvastar Free is fully functional for casual use — every tool is available, just with caps on saved-item counts and CSV-only export. Pro lifts the caps and unlocks Trace and JWKS Proxy.
