Calculation inputs
Public calculators run in your browser. We currently do not automatically write your input amounts or results to the product database. On tools that support both languages, choosing a language switch uses temporary storage in the current tab to transfer inputs. The transfer is deleted after reading and is valid for two minutes. Inputs are not placed in a public URL or uploaded. Do not provide SSNs, passwords, card numbers or other sensitive information in tools or emails.
Saving, exporting and sharing by choice
On tools supporting local saves or exports, records are saved only when you choose to do so. Keep exported files secure; other users of a shared device may see local records.
Sharing offers email, a copied public page link and device-supported system sharing without inputs, results or account information. Older parameter links are encoded, not encrypted; do not publicly distribute links containing personal information.
Website requests and contact
Hosting and network providers may process basic access data such as IP addresses, browser information and request logs. When you email us, email providers process the content you choose to send.
Optional usage statistics
Usage statistics are off by default. You may allow or disable them on this page; the preference is stored only in this browser. Statistics stay off when your browser sends Do Not Track or Global Privacy Control signals.
If allowed, events include page paths, tool names, button placements, public product IDs, link types and broad referral channels. Input amounts, results, search text, full query parameters, emails and account IDs are not uploaded. Our own event collector does not set visitor-identification cookies. Broad channels are stored in the current tab and cleared when statistics are disabled.
When configured on the production site, Google Analytics loads only after permission and may use browser-identification cookies for visits, device and channel reporting. Google Signals and advertising personalization are disabled. Disabling statistics stops our Google events and attempts to clear first-party GA cookies. Google and hosting providers may still process network information such as IP addresses.
Disabling statistics does not affect tools or applications. Browsers may block collection. Application clicks do not prove approval, eligible affiliate conversions or revenue; income is confirmed in advertising or affiliate reports and settlement records.
Accounts and saved items
Supabase Auth handles email and password authentication. Passwords are not stored in the product database. Your browser stores your session; sign out on shared devices.
Saved items store only your account ID, calculator or card ID, and the time saved. They contain no calculator inputs or results. Items are stored in Supabase; each user can access only their own records and remove them in My saves.
Account-confirmation and password-reset emails are not marketing subscriptions. This update does not add marketing email, advertising or public user profiles. Contact us for privacy questions or account-data deletion requests.
Optional usage statistics
Off by default. When configured and allowed, statistics record pages, calculations, clicks and broad referral channels—not input amounts, results, search text or account information. Tools work with statistics disabled.
When Google Analytics is connected on the production site, allowing statistics also permits its browser-identification cookies. Your financial inputs, email and account ID are not sent; advertising personalization is disabled.
This choice is stored only in this browser. Clearing site storage resets it to off.
