Your numbers stay yours

Calculator and CSV

Manual assumptions and uploaded CSV rows are processed in your browser. Simulation values are not saved to our server. CSV files are not uploaded. Report downloads are created locally. A share link is created only when you ask to copy it; the fragment contains bounded numerical assumptions and is visible to anyone you share it with. It excludes action labels, names, CSV rows, emails and run IDs.

Currency changes relabel values and do not convert them. Reports identify their modeled inputs and limitations.

Optional analytics

Optional event measurement uses the shared Grislabs PostHog EU project only after explicit consent, with a host-scoped identifier. It respects Do Not Track and Global Privacy Control. Declining or withdrawing stops future events and clears the local identifier. No pre-consent replay, autocapture, session replay, financial assumptions, raw URLs, fragments, form values, filenames or file contents are sent. Analytics can be unavailable and the calculator still works.

One-time pricing-review contact request

If you submit the €49 one-time pricing-review request form and check the explicit contact request, your email and selected answers are sent to the pilot endpoint and stored in the product’s PostgreSQL database. This permission is only to contact you to arrange delivery details; it is not marketing opt-in. The request is not a contract, subscription, payment, or verified sale. There is no charge on submission. If the database is unavailable, the form reports a retryable failure.

Requests are automatically deleted after 90 days by a daily retention task. You can also request deletion through Grislabs’ existing public contact channel. No email is sent automatically.

Request handling

The calculator, guides, and one-time pricing-review offer are available at pricing.grislabs.com. A contact request is not evidence of a sale. No payment processing or automatic billing is used.
