The short version: the free tools on this platform collect no personal data whatsoever. Personal information is only collected when you request a report or make a purchase, and is used only to fulfil that request. We do not track you, profile you, or sell your data.
This privacy policy applies to the Predictive History Method platform operated by Sang Heeringa, trading as Predictive History Method™, Netherlands. References to "PHM", "we", "us", or "our" refer to this operator.

This platform uses one category of cookie only: strictly necessary session cookies that enable the diagnostic tool to function during your visit. These cookies expire when you close your browser. They contain no personal information and cannot be used to identify you.
We do not use analytics cookies, advertising cookies, or third-party tracking of any kind. We do not use Google Analytics, Facebook Pixel, or similar services. There is no analytics tracking on this platform.
Because we use only strictly necessary cookies, we are not required to obtain consent for them under GDPR. We disclose their use here for full transparency.
If you request a Strategic Report or purchase a product, we retain your name and email for the duration of any ongoing engagement plus a maximum of 24 months, after which it is deleted. You can request earlier deletion at any time — see section 6.
If you download the Executive Brief, your email is retained for up to 12 months. You can unsubscribe at any time.
We do not sell your data. We do not share it with third parties for marketing purposes. The only third-party processor involved is Stripe, which handles payment transactions under its own privacy policy and GDPR data processing agreement. Stripe does not receive your name or email from us — only the transaction data required to process payment.
If you are based in the EU/EEA, you have the following rights regarding any personal data we hold about you:
To exercise any of these rights, email privacy@predictivehistorymethod.com. We will respond within 30 days.
You also have the right to lodge a complaint with the Dutch Data Protection Authority (Autoriteit Persoonsgegevens) at autoriteitpersoonsgegevens.nl.
Any personal data we hold is stored securely. We do not store payment card details — these are handled entirely by Stripe. We use HTTPS across the entire platform. Access to any stored personal data is restricted to the operator.
This platform is operated from the Netherlands. If you access it from outside the EU, your session data (non-personal) is processed on servers that may be located outside the EU. No personal data is transferred internationally except through Stripe's payment infrastructure, which operates under standard contractual clauses as required by GDPR.
We may update this policy as the platform evolves. The effective date at the top of this page reflects the most recent version. Material changes will be noted on the platform.
