Frequently Asked Questions
Can I try PRO before paying?
Yes! All new subscribers get a 7-day free trial with full access to PRO features.
How do I cancel my subscription?
Manage your subscription through your Apple ID settings. Cancel anytime - no questions asked.
Do AI features cost extra?
PRO includes unlimited AI usage, but you need your own API key from Anthropic or OpenAI. API costs are typically $2-5/month for moderate use.
What happens to my diagrams if I downgrade?
Your diagrams are always stored locally on your Mac - they're yours forever. If you downgrade to FREE, you can keep using all existing diagrams, but can only create 3 new ones.
