I.R

Most rental management tools are built for agencies managing hundreds of units. But most landlords in Spain have just 1 10 properties and end up managing everything in spreadsheets, sticky notes, and WhatsApp reminders.

I built Hommy to fix that.

I've been building a SaaS with Lovable + Supabase that handles pretty sensitive stuff bank data via Open Banking, tax-related info. It's still in beta with very few users, but I want to get security right before opening it up more.

I know the basics (HTTPS, not exposing API keys in the frontend), but I'm not confident I've covered what actually matters for something handling financial/tax data.

For anyone who's dealt with this:

What would you consider the absolute minimum before letting real users connect their bank accounts to something you built solo?

I m active here, and English isn t my first language.

It s actually interesting that the whole global community of builders, makers, and founders has basically one common language: English.

And sometimes I wonder: how good does your English actually need to be?

I definitely overthink it sometimes:
Is this sentence natural? Is my grammar okay? Will people understand what I mean?
