Frequently asked questions
Why does collecting extra fields matter for an MVP?
Every extra field adds signup friction, increases drop-off, and expands your privacy and security surface area — all for data you won't act on yet.
What counts as a field 'used in the core outcome'?
A field that directly feeds the core action, calculation, or decision your MVP delivers — not something collected 'just in case' for a future feature.
Should I never collect optional data?
You can, but treat it as a deliberate trade-off — mark it optional, and make sure it's not blocking signup or onboarding completion.
Is this the same as a privacy audit?
No — this is a quick MVP-stage scope check. A full privacy or compliance review is still worth doing separately before handling sensitive data.
What if I need a field later but not now?
Defer collecting it until the feature that uses it actually ships — you can always add a field later, but removing one after users expect it is harder.
