A CLEAR DATA BOUNDARY
Your records.
Your environment.
This public preview
The interactive demo uses synthetic records and processes them in your browser. It does not request an upload. To show current exchange rates it asks api.frankfurter.dev for the public ECB reference rates; your browser contacts that service directly and sends nothing else. Without a connection the demo shows synthetic rates instead. The briefing form either opens your own email application with a prefilled message or saves a local text file; this site itself does not transmit or store your input. This site uses no external fonts or cookies. To count visits, the site's server notes for each page view the page, the name of the site you came from (not the full address), any campaign tag in the link, your country and device type. To count daily unique visitors it keeps a one-way code made from your IP address and browser together with a random value that is replaced every day and deleted within 48 hours. Your IP address is not stored, and a visit cannot be linked to another day or to you. If you also allow it, Cloudflare Web Analytics counts page views without cookies or a visitor profile; until you choose, nothing is counted. Your choice is kept only in this browser. A hosting provider may keep access logs once the site is published.
Scoping a customer project
Start with a problem description, a column layout or made-up example rows. Do not send real production records, personal information, passwords or database dumps. The purpose of a small synthetic sample is to understand structure, not to prove performance.
Delivering a local dashboard
The proposed default is development with synthetic examples and validation of real data inside the customer environment. Offline behaviour and network requests must be checked for the delivered package. Support uses synthetic reproductions by default; any access to real records or screen sharing needs a separate agreement.
