Email contact@dataflowcontrols.com for additional assistance.

Who is responsible

For the purposes of this Policy, the controller of personal data collected through the Site is DataFlow Controls. Where applicable law requires a postal address or a representative, you may request those details using the contact email above until we publish a fuller legal entity block on this page.

Summary

Topic	What we do
Essential / preference	We use a small first-party cookie to remember your theme (light/dark).
Analytics	We use privacy-focused, cookieless analytics to understand traffic and feature usage.
Sale/share of personal information	We do not sell and do not share personal information for cross-context behavioral advertising.

Information we collect

1. Information you give us

Contact and business context when you choose to engage with us (for example through email links on the Site or by booking a meeting via our Proton Calendar scheduling link).

We ask that you do not send us sensitive categories of personal data (such as health information) unless we explicitly request them.

2. Information collected automatically on the Site

Technical data typical of web browsing: for example approximate location inferred at network level (which may include city/region/country), device and browser type, and pages viewed.
Usage events such as page views, outbound link clicks, and UI engagement events tied to specific components. We use this information to improve the Site and product experience, not to build advertising profiles.

3. Cookies and similar technologies

Strictly necessary / preference: We use a first-party cookie (commonly associated with Color Mode) to remember your theme preference. This is needed for a consistent experience and is not used for cross-site advertising.
Analytics: We use a privacy-focused, cookieless analytics setup. We do not set analytics cookies for this measurement.

4. Third-party content

Parts of the Site link to third-party services (for example Proton Calendar appointment booking). When you book a meeting, your browser opens Proton’s site directly. Proton has its own terms and privacy notices, and any information you provide there is handled according to their policies.

How we use information

We use information to:

Operate, secure, and improve the Site;
Respond to inquiries and deliver materials you request (such as scorecard summaries);
Understand aggregated usage of the Site through cookieless analytics;
Comply with law and protect our rights.

We do not sell your personal information and do not share it for cross-context behavioral advertising.

Depending on the activity, we may rely on:

Legitimate interests in maintaining and improving a business website (including privacy-focused cookieless analytics);
Legitimate interests in operating a business website, securing our systems, and responding to requests—balanced against your rights;
Performance of a contract or pre-contractual steps at your request when we prepare deliverables you asked for (such as a scorecard email).

Analytics

We use a privacy-focused analytics setup configured to run without setting analytics cookies. This analytics setup may infer approximate location (including city-level where available) from network metadata. We do not collect precise geolocation coordinates from your device for analytics.

Retention

Site logs (server or hosting): typically retained for a limited period for security and reliability—exact duration depends on our hosting provider’s configuration.
Email and messaging: retained according to legitimate business needs and provider capabilities.
Preference cookie: theme preference cookie remains until cleared by you or replaced by the browser.
