We never sell your data
Your personal information is used only to deliver the product you purchased, and to provide support. It is never sold to any third party under any circumstance.
We never share data with advertisers
HeartFirst products are ad-free. No advertiser has access to your data or behaviour on our platforms. We do not participate in any advertising network.
We never exploit anxiety to sell
No countdown timers. No false scarcity. No manufactured urgency. Our users are often already dealing with real fear. We do not add to it to drive income.

Our formal compliance and ethics position
Shyntesy operates HeartFirst to the highest standards of data protection, consumer rights, and ethical conduct.
GDPR & UK GDPR
We process personal data lawfully, fairly, and transparently under EU General Data Protection Regulation and the UK Data Protection Act 2018. We collect only what is necessary, retain it only as long as required, and provide full data subject rights.
EU Consumer Rights Directive
We comply with the Consumer Rights Directive (2011/83/EU) including pre-contractual information obligations, digital content conformity requirements, and the right of withdrawal for digital purchases.
Secure Payment Processing
Payments are processed by PCI-compliant payment providers such as Stripe and, where available, PayPal. We do not store payment card data. Terms of Service, Privacy Policy, and Refund Policy are registered with processors as required for merchant accounts.
Ethical Marketing Commitment
We do not use countdown timers, false scarcity, dark patterns, or manufactured urgency. We do not advertise, sell advertising space, run third-party advertising on our platform or products, or give advertisers access to personal data. Any analytics, payment, email, or support tools we use are documented in our policies.
Health Content Responsibility
All HeartFirst products are positioned and written as educational tools, never as medical advice, diagnosis, or treatment. Every product carries a clear disclaimer. Clinical guidance cited is grounded in ACC/AHA, ESC/EAS, NICE, and published consensus standards.
Accessibility & Inclusion
We design to WCAG 2.1 AA as our target standard. We recognise that our users may be dealing with fear, stress, visual impairment, or cognitive overload, so we build products that do not make any of these harder.
In plain language: We respect the people who use HeartFirst products. We protect their data, honour their consumer rights, charge fair prices with a genuine refund guarantee, and refuse to use the anxiety that often brings them here as a lever to extract more money. These are not aspirations — they are the documented policy on every page of this subdomain. If you find us falling short of any of it, tell us.
