Support

Help for calculators and CSV tools.

This noindex preview does not yet have a monitored support inbox. Do not send secrets, credentials, customer records, or CSV data to an address associated with this project. Keep a local note of your browser, operating system, error text, and a minimal synthetic reproduction until a verified contact path is published here.

Calculator studio

Author up to 20 inputs, 20 outputs and 50 expected-result examples. Arithmetic formulas support min, max, ceil and floor. Save passing versions in this browser and export a matching saved snapshot. The studio does not send calculator data to a server.

If a check fails, compare the formula with your independently calculated expected answer. If an input cannot be removed, first edit the formula that references it. If saving fails, keep the tab open and check whether browser storage is blocked or full.

CSV utility

• Modern Chrome, Edge, Firefox, and Safari with JavaScript and local storage enabled.
• UTF-8 CSV up to 64 KB, 500 rows, 50 columns, and 2,000 characters per cell.
• Quoted CSV fields and a self-contained HTML export.

Not supported

• File uploads, spreadsheet workbooks, arbitrary HTML/JavaScript, external URLs, provider calls, accounts, collaboration, or checkout.
• Recovery of a cleared browser draft or drafts saved on another device.
• Guaranteed rendering in legacy email clients or compliance certification.

Response expectation

No service-level agreement or monitored response channel exists for this founder preview. Paid pilots and support commitments are closed until a verified contact path and written delivery terms are published.
