Privacy Policy
Last updated: 5 May 2026 Effective date: 5 May 2026
This Privacy Policy explains how we collect, use, share, and protect your personal data when you use our website (zwim.com), our connected hardware and applications, our waitlist, and our customer-support channels.
This policy is provided jointly by:
- ZEN8 Sports Ltd (registered in the United Kingdom), and
- ZEN8 Sports Portugal Unipessoal Lda (registered in Portugal),
trading together as ZWIM ("ZWIM", "we", "us", "our").
A separate Cookie Policy explains how we use cookies and similar technologies on our website.
If you have any questions about this policy or your personal data, contact us at privacy@zwim.com.
1. Who we are (data controllers)
We operate as joint controllers under Article 26 of the EU and UK GDPR. This means both companies share responsibility for how your personal data is used.
ZEN8 Sports Ltd (UK)
- Company number: 12662386
- Registered office: 7 Bell Yard, London, England, WC2A 2JR
- UK VAT: 370135426
- Role: contracting and selling entity, payment processing controller, brand owner
ZEN8 Sports Portugal Unipessoal Lda (Portugal) — research and development entity
- Registered office: Rua Professor Sousa da Câmara 207, 3E, 1070-216 Lisboa, Portugal
- Role: EU establishment, research and development (hardware, firmware, software, training algorithms), product engineering, EU operations, customer support, and connected-product data processing
Essence of our joint controller arrangement (GDPR Art. 26). ZEN8 Sports Ltd is the contracting party for orders placed through zwim.com, holds payment and finance records, and is the primary point of contact for marketing consent. ZEN8 Sports Portugal Unipessoal Lda is our research-and-development arm and EU establishment; it runs the technical operations behind our hardware, firmware, app, and training algorithms, processes connected-product data, and is the primary point of contact for product, account, and training-data questions in the EU. You can exercise your rights against either entity. Both companies remain jointly responsible regardless of which one you contact.
Single privacy contact for all requests: privacy@zwim.com.
We appoint a Data Protection Officer only where the law requires us to. The contact above is the right channel for all privacy queries, including from EU and UK residents.
2. What personal data we collect
A) Information you give us directly
- Account and waitlist data: name, email address, country, password (hashed), referral code status.
- Optional profile data: age, gender, height, weight, swim ability or club affiliation, training goals.
- Order data: delivery address, billing address, items purchased, order value, currency.
- Payment data: processed by our payment providers (e.g. Shopify Payments, Klarna). We do not see or store your full card number.
- Communications: survey responses, interview notes, feature requests, support messages, product feedback, reviews.
B) Health and performance data (connected training)
When you connect and use ZWIM hardware (e.g. Smart Swim Paddles, Bench, Propulsion Bands) we may process training metrics such as:
- Propulsive Watts, stroke rate, left/right balance, efficiency, wasted energy.
- Session duration, active meters, time, pace.
- Calibration data and device telemetry.
Special note on health-related data. Some of these metrics may qualify as "data concerning health" or special-category personal data under EU and UK GDPR. We process this data only after you give explicit, informed consent inside the app, and only to deliver the training experience you have asked for. You can withdraw your consent at any time in the app's settings or by emailing privacy@zwim.com. Withdrawing consent does not affect processing carried out before withdrawal. Withdrawing consent may disable certain features (for example long-term progress history).
C) Information collected automatically
- Device data: IP address, browser type, device model, operating system, app version, language, timezone.
- Usage data: logins, session frequency, feature use, button taps, screen views, diagnostic logs and crash reports.
- Cookies and similar technologies: see our Cookie Policy.
D) Information from third parties
- Affiliate, referral, and partner platforms that legitimately share your contact details with your consent.
- Social-media platforms, if you choose to log in or interact with us through them.
- Service providers acting on our behalf (analytics, fraud prevention, customer support).
3. Legacy ZEN8 customer data
If you previously purchased from zen8swimtrainer.com or interacted with the ZEN8 brand before 2026, ZEN8 Sports Ltd may continue to hold:
- contact details (name, email),
- purchase history (orders, items, fulfilment),
- support history.
We use this data to:
- continue to support you on legacy ZEN8 hardware,
- verify eligibility for loyalty upgrades and Founder offers,
- migrate your account smoothly to ZWIM if you opt in.
Marketing to legacy customers. Where the law allows it, we may send legacy customers product news about ZWIM as a successor product line, relying on the existing customer relationship ("soft opt-in" under PECR in the UK and equivalent rules in the EU) and on legitimate interests. Every email contains an unsubscribe link, and you can opt out at any time by clicking it or by emailing privacy@zwim.com. Once you opt out, we will stop sending marketing.
