## Supporter Wall

Supporters who opt in are listed in the app — founders first, then Blossom, Bloom, Seedling and tippers. It is opt-in: nothing appears until you switch it on, and you can switch it off again at any time.

## Why Support ProbaBaby?

Where your support goes: servers, sync and family sharing; push notifications and Live Activities. Not predictions — those are a paid feature and pay for themselves.

- **Solo Developer, No VC** — ProbaBaby is built by one person. No investors. No corporate overlords. Every feature, every line of code — it's all one developer. Your support means more time on ProbaBaby.
- **No Ads, Ever** — ProbaBaby will never show ads. Not banner ads. Not video ads. Not sponsored content. Supporter contributions and credit purchases fund development instead.
- **Privacy Means No Data Selling** — Our business model is simple: you pay for predictions or support the app. Your data stays yours. No selling, no sharing, no monetizing your pregnancy journey.

## FAQ

**Is supporting ProbaBaby tax-deductible?**

No. ProbaBaby is not a registered nonprofit. Contributions are payments for digital goods/services (supporter perks), not charitable donations.

**Can I cancel my supporter subscription anytime?**

Yes. Cancel anytime from Settings. No questions asked. You'll keep your badges, but streak badges will stop progressing.

**What happens to my Founding Supporter badge if I cancel?**

You keep it forever. Founding Supporter badges are permanent, even if you cancel your subscription.

**Can I upgrade from Seedling to Bloom or Blossom?**

Yes. Upgrading earns you the Tier Climber badge. Downgrading is also allowed — you keep your highest tier badge.
