A clear record of what we receive.

01 · Scope

The short version.

FormulaSignal does not sell personal information, run ads, or use affiliate links. Email hello@formulasignal.com for privacy questions, corrections, or requests about information associated with you.

02 · Information we receive

Different surfaces, different data.

• Public research questions may be recorded as demand signals, including the question, resolved product, and channel. No account is required to read a report.
• A question containing health information is handled in memory for that response. The health detail is not stored, joined to an account, used for training, or used for targeting.
• Watchlists and alerts use an email address, an opaque owner reference, and stated non-health preferences when a person chooses to provide them.
• Paid customers may provide a name, email, company, role, priorities, and billing details. Full payment-card details are handled by Stripe, not FormulaSignal.
• When you email support, we receive the message and the contact details included in it so we can reply.

03 · Use

Why we use it.

We use information to provide customer access, deliver alerts and editions, process billing, answer support requests, investigate corrections, protect the service, and decide what the Record should research next.

We do not use health information for training, targeting, advertising, or account personalization. Storing a health preference would require a separate, specific, revocable opt-in.

04 · Service providers

Who helps operate FormulaSignal.

Current providers include Cloudflare for hosting and the customer database, Stripe for billing and payment processing, Resend for transactional email, and Hostinger for incoming support mail. They receive information only as needed to provide their service.

05 · Retention and security

Keep the record, limit the rest.

Evidence records remain part of the historical Record. Demand signals are kept for up to 24 months and then aggregated or have their raw text deleted. Health inputs are not stored. Customer records follow the customer system and billing obligations.

Customer access uses expiring magic links and secure sessions rather than a password database. Stripe handles card data, and no online system can promise perfect security.

06 · Your choices

Ask us to review your information.

Email hello@formulasignal.com if you want to ask about access, correction, deletion, or withdrawal of a non-health preference. Include enough detail for us to identify the relevant account or message, but do not send passwords or full payment-card details.

07 · Changes

This page can change as the service does.

If the way FormulaSignal handles information materially changes, this page will be updated with a new date.
