Frequently Asked Questions

Quick answers about pricing, trials, and refunds.

Are the basic functions really free forever? ▾

Yes. Every extension's single-file core functions are 100% free, forever. No watermarks, no forced login, no time limits. Only advanced features (larger batches, batch export, cross-device sync, higher limits, etc.) require a premium license.

What's the difference between Single Extension and Full Suite? ▾

Single Extension License ($2.99/mo or $9.99 lifetime): Unlocks premium features for one chosen extension only. Other extensions remain free basic.

Full Suite ($4.99/mo or $29.99 lifetime): Unlocks premium features for all current extensions + any future new extensions automatically.

Can I try premium features before buying? ▾

Yes. Email [email protected] to request a 3-day free trial for any single extension. No credit card required. Trial keys are issued manually — delayed replies may occur. Each user can only apply once per extension.

What's the refund policy? ▾

7-day refund guarantee for unused premium licenses. If you haven't used any batch premium features within 7 days of purchase, email [email protected] for a full refund. After 7 days or after using batch features, digital products are non-refundable.

Will the Full Suite price increase in the future? ▾

The Full Suite price may increase for new customers as more extensions are released. However:

Existing monthly subscribers keep their original price permanently — no price hike on renewals.
All lifetime license keys never expire — permanent access to the purchased version, unaffected by any future price changes.
Single Extension pricing will remain stable.
