Free use & voluntary support
There is no subscription or paid feature tier. Support is voluntary, unlocks no features or priority, and is not an investment, charitable donation or public fundraising.
Free source data
We do not charge for access to third-party public source data. Source data remains separately identified and available through its original provider.
Voluntary support
Every feature—including AI analysis, personalized summaries and market monitoring—is free. Voluntary support only funds independent development and server costs and unlocks no benefits.
