Common questions

Transparent from the first input

CoinCalcs is designed to remain useful when live providers are unavailable or feature flags are off.

Do I need to connect a wallet?

No. Every Phase 1 calculator accepts manual inputs and never asks for a seed phrase, private key, or signature.

Are results live or guaranteed?

No result is guaranteed. Manual and reference results are labeled explicitly; future live results will include source, timestamp, freshness, and methodology version.

Is calculation history stored?

Not on a server. Firebase and authentication are disabled. Only local preferences such as theme or consent are stored on this device.

Does CoinCalcs give investment advice?

No. The tools are informational and educational. They do not recommend assets, routes, trades, or position directions.
