Your landing page makes a lot of claims that are not true

- that the code is 100% mit licensed (it's not)

- that this is in any way gdpr compliant (there are literal rules around this)

- that your data is encrypted and private (it isn't encrypted? Unless being written in Italian is encryption now?)

- that they'll have 99.9% uptime (there is no SLA for vercel hobby tiers)

- "No middlemen. No third-party storage. Every submission lives in your GitHub..." (that is the very definition of third-party storage and a middleman)
