What founders get
- Your price, locked for life. Free or half price, every renewal, for as long as your subscription stays active.
- The Founding Member badge and sash emblem, so everyone on the leaderboard knows you were here first.
- Everything in your plan: every test and game, timed practice exams, no house ads.
- First look at new tests and games before anyone else.
The fine print, in plain words
- One founder spot per subscription. Your place in line is the moment you finish checkout.
- Keep your subscription active and play at least once a year, and your founder price never changes.
- If you cancel or let it lapse, the founder price ends and the spot isn't given to anyone else.
- Payments and sales tax are handled by Stripe through Link, so your card statement says LINK.COM* SESK.INFO.
- Changed your mind? Ask within 14 days for a full refund. Full terms: Terms of service.
