Frequently asked questions

What happens after my 7-day free trial?: After your trial ends, you'll be prompted to upgrade for $39/month. If you don't upgrade, your account is paused — your client data is saved and nothing is deleted.
Can I cancel anytime?: Yes. Cancel from your account page at any time. You'll retain access until the end of your current billing period and won't be charged again.
Is the AI content actually personalized?: Yes. Every piece of content is generated using your client's specific goals, fitness level, injuries, equipment, and any notes you've added. It's not generic templates.
Can I edit the AI-generated content?: Absolutely. Everything generated is yours to copy and edit however you want. Think of it as a strong first draft, not a finished product.
Is my clients' data safe?: Yes. All data is encrypted in transit and at rest. Client information is used only to generate content within your account — it's never sold or shared. See our Privacy Policy for details.
