Privacy

Prelaunch privacy notice — updated 25 September 2026. Operator identity, privacy contact and production processing details must be completed before public launch.

Your calculator data

Inputs and local plan history are stored in this browser. The current code does not upload them to an account database. Local storage is not an encrypted vault and can be read by scripts on this origin or someone with access to your browser profile. Avoid passwords, recovery codes and unnecessary account identifiers.

Website requests

Netlify hosts the website and may process request metadata such as IP address, browser information and access times. Fonts and chart code in this version are served locally or use system fonts. No advertising or analytics tracker is included in this source package. Opening an external reference visits that provider’s website.

Portfolio files

CSV / TSV files and pasted spreadsheet cells are processed locally in your browser. Imported holdings, entered return histories and analysis settings are saved in browser storage when you save the draft. They are not uploaded to an account or market-data provider. Your local data export includes these records. Do not include account numbers or personal identifiers in the imported columns.

Optional security search and quotes

Portfolio risk supports manual ticker entry without sending your holdings. If the optional market-data service is configured, pressing Find security or Request latest available quote sends the search text or ticker/exchange/currency through a Netlify Function to Twelve Data. It does not send your balances or quantities. Hosting and provider request logs may contain request metadata. There are no automatic quote refreshes. Provider coverage, display rights and production processing details must be confirmed before that service is activated.

Accounts and payments

Accounts, cloud sync and paid subscriptions are not active. Before those features open, this notice must identify the controller, contact details, processing purposes and legal bases, processors, retention periods and any international transfers or safeguards.

Local data controls

Use local data controls to export or erase this site’s saved calculator records. Deletion applies to this browser; it does not erase downloaded copies or hosting logs. Clearing browser storage or changing devices can remove access to your plan.

Privacy enquiries

The public operator and privacy contact are not yet published. This is a release blocker. Production terms must explain applicable access, correction, deletion and complaint rights and the relevant supervisory authority. This draft does not replace that information.
