Common questions about pricing
What is bring your own key (BYOK)?
BYOK lets you connect your own OpenAI API key to unlock all AI features. You pay OpenAI directly for the tokens you use, which is often the most cost-effective option for regular users. We never see or store your API key on our servers beyond what is needed to make requests.
How much does AI usage cost with BYOK?
Costs depend on how much you use the AI features. Generating a workout plan or having a conversation with your coach typically costs a few cents. OpenAI provides detailed usage tracking in their dashboard so you can monitor spending.
Is manual tracking really free forever?
Yes. Manual workout tracking, session history, PR tracking, and the guided session flow are free with no time limits. We believe everyone should have access to solid workout tracking tools regardless of budget.
Can I switch between plans?
Absolutely. Start with free manual tracking, add your own API key when you want AI features, or upgrade to premium when it becomes available. Your workout history and progress stay intact no matter which option you choose.
What happens to my data if I downgrade?
Your workout history, plans, and progress are always preserved. If you remove your API key or downgrade from premium, you simply lose access to AI features until you reconnect. Nothing is deleted.
Do you offer refunds?
Since the free tier and BYOK options have no upfront cost, there is nothing to refund. For premium subscriptions (when available), refund policies will be detailed at launch. Contact support if you have billing questions.
