Terms of sale

Last updated September 3, 2026

These terms cover Sharpen, a daily brain-training programme made by Watel, a trading name of Muse Financial Technologies Inc. ("we", "us"). By buying a plan you agree to them.

What you are buying

Refunds

Full refund, no questions asked, within 30 days of payment. See the refund policy.

The brain test

The free test on our site is a short, informal snapshot of how you performed on a few tasks today. It is not a medical, psychological or IQ assessment and must not be used as one.

Payments

Payments are processed by Stripe. We do not see or store your card details. Prices are in US dollars; your bank may apply a conversion fee.

Governing law

These terms are governed by the laws of the jurisdiction in which Muse Financial Technologies Inc. is incorporated. Nothing in them limits consumer rights you have under the law of the country you live in.

Changes and contact

If we change these terms, the version in force is the one published on this page when you bought. Contact: tonje@trymuse.com.
