Launched BytePriva today — 50+ free browser-based tools

Launched BytePriva today — 50+ free browser-based tools (calculators, PDF tools, business tools like an invoice generator and a lightweight POS system). No signup, nothing uploaded, everything runs client-side.

Something I'm still figuring out as a solo maker: with this many small tools instead of one focused product, what actually makes people trust that a free tool is legit and not just going to sell their data or bury them in ads later? Is it the "no signup" messaging, seeing the source code, reviews, or something else entirely?

Curious how other makers here think about building trust for free tools, especially ones handling things like invoices or business data. (Link to what I built, for context: https://www.producthunt.com/products/bytepriva)
