Disclaimer: ThinkFast is provided for personal entertainment and casual brain-training purposes. We make no claims that using the Application will improve cognitive function, memory, or any medical or clinical outcome. The app is not a substitute for professional medical or psychological advice.
Both plans provide full access to all ThinkFast features including every puzzle, both difficulty tiers, unlimited daily challenges, full puzzle history, detailed progress stats, and Leaderboard participation. Subscriptions are processed through Apple App Store (iOS) or Google Play Store (Android) and are subject to those platforms' billing terms.
ThinkFast may offer a free trial period for new subscribers at our discretion. If a free trial is offered and you do not cancel before the trial ends, your subscription will automatically begin and you will be charged the applicable fee. Trial eligibility is determined by Apple or Google and is typically limited to new subscribers only.
Subscriptions automatically renew unless canceled at least 24 hours before the end of the current billing period. Your account will be charged for renewal within 24 hours prior to the end of the current period at the same price as your current plan.
We reserve the right to change subscription pricing. We will provide reasonable advance notice of any pricing changes through the app or via email. Continued use of the app after a price change constitutes acceptance of the new pricing.
All subscription purchases are processed through the Apple App Store or Google Play Store. Refund requests are subject to the respective store's refund policies. We do not control refund decisions made by Apple or Google.

To the fullest extent permitted by applicable law, ThinkFast shall not be liable for any indirect, incidental, special, consequential, or punitive damages arising from your use of or inability to use the Application, including but not limited to loss of data, loss of streaks or progress, or any dissatisfaction with puzzle difficulty or scoring.
