Privacy Policy

Last updated: March 14, 2026

At Zew Studio, accessible from https://zewstudio.com, one of our main priorities is the privacy of our visitors. This Privacy Policy document contains types of information that is collected and recorded by Zew Studio and how we use it.

If you have additional questions or require more information about our Privacy Policy, do not hesitate to contact us through email at contact@zewstudio.com.

We amend these Policies from time to time. Please check these to ensure you understand the terms which will apply at that time.

This Privacy Policy is only in the English language.

1. In A Nutshell

We use cookies, log files, Strava and uploaded activity data, and information provided by you when you decide to purchase a print. We use third-party services to handle payments, printing, fulfilment, shipping, and analytics. Please consult the relevant sections below and make sure you understand what you're consenting to.

2. Data Controller

For the purposes of the UK General Data Protection Regulation (UK GDPR) and the Data Protection Act 2018, the data controller is Szymon Padlewski trading as Zew Studio, contactable at contact@zewstudio.com.

3. Legal Basis for Processing (UK GDPR)

We process your personal data under the following legal bases depending on the type of data and the purpose:

  • Contract performance (Article 6(1)(b)): We process your name, email, shipping address, and phone number to fulfil your order and deliver your Products. We process your Strava activity data to create your custom poster.
  • Consent (Article 6(1)(a)): We access your Strava account data only after you explicitly authorise us via the "Connect with Strava" OAuth flow. We set analytics cookies (Google Analytics) only with your consent via our cookie banner.
  • Legitimate interests (Article 6(1)(f)): We use server log files and essential cookies to maintain security, prevent fraud, and ensure our site functions correctly.
  • Legal obligation (Article 6(1)(c)): We retain order and transaction records as required by UK tax and accounting law (up to 6 years).

4. Your Data Protection Rights

Under the UK GDPR, you have the following rights in relation to your personal data:

  • The right to access the personal data we hold about you
  • The right to rectification of inaccurate data
  • The right to erasure ("right to be forgotten")
  • The right to restrict processing
  • The right to data portability
  • The right to object to processing
  • The right to withdraw consent at any time

To exercise any of these rights, please contact us at contact@zewstudio.com. We will respond to your request within one month of receiving it, as required by UK GDPR. In certain cases we may extend this by a further two months, in which case we will inform you.

Please note that certain data (such as order records required for tax purposes) cannot be deleted until the legal retention period has expired, even if you request erasure.

5. How We Use Cookies

A cookie is a small file which asks permission to be placed on your computer's hard drive. We use essential cookies for authentication and site functionality, and analytics cookies (with your consent) to understand how visitors use our site.

For full details on the cookies we use, their purposes, and how to manage your preferences, please see our Cookie Policy.

6. Log Files

Zew Studio follows a standard procedure of using log files. These files log visitors when they visit websites. All hosting companies do this and a part of hosting services' analytics. We collect technical log information such as IP address, browser type, Internet Service Provider (ISP), date and time stamp, referring/exit pages, and similar diagnostic data to secure, maintain, and improve the website. This information is not ordinarily used by us to directly identify individuals, though IP addresses and related online identifiers can be personal data in certain contexts. The purpose of the information is for analyzing trends, administering the site, tracking users' movement on the website, and gathering demographic information.

7. Financial Data

Payments are processed by Stripe. We do not store full payment card details on our systems. Stripe processes payment information in accordance with its own privacy policy. We receive limited transaction and order information from Stripe as needed to manage orders, provide customer support, and keep accounting records. Please consult Stripe's Privacy Policy if you wish to know more.

8. Personal Information

When you complete a purchase on our checkout page you will be required to provide your name, address as well as your contact email and number in order to fulfil your order. This information is collected securely through Stripe during the checkout process and is used solely for order fulfilment and shipping purposes.

For physical orders, your name, shipping address, email, and phone number are shared with our print and fulfilment partner, Prodigi, solely for the purpose of printing and delivering your order. See section 10 (Third-Party Services) for more details.

Since we do not store payment information ourselves, we do not use it for any unsolicited marketing.

Your contact email and phone number are only used to update you on the progress of an order and for customer support purposes.

9. Activity Data and Strava

When you design your own print, the information you enter is kept by us in a secure database. We do not use this information in any way other than to produce a digital version of your design and to fulfil your order. We do not give this information out to any external or third-parties except as necessary to fulfil your order (e.g., to our print provider, Prodigi).

This includes the information from any GPX or FIT files you upload as well as the information you consent Strava to provide us access to when you use the "Connect with Strava" button. By connecting your Strava account, you authorise us to access your activity data for the sole purpose of creating your custom poster.

We only access the minimum amount of data necessary to create your poster (activity routes, statistics, and metadata). We store your activity data (routes, distances, elevations, dates, and similar statistics) as part of your order record. We do not store your Strava profile information such as your profile name, profile picture, bio, or other personal profile details. We only store your athlete ID (a numeric identifier) and activity data needed for poster creation.

When you connect your Strava account, we store encrypted OAuth tokens (access token and refresh token) in our database to maintain your session. These tokens are encrypted at rest. If your connection is inactive for 1 month, we will automatically deauthorise the connection and delete the stored tokens.

10. Third-Party Services

We use third-party providers to process data on our behalf or as independent service providers, including Stripe (payments), Prodigi (printing and fulfilment), Strava (activity import), Mapbox (mapping), and Google Analytics (analytics, with consent where required). We share only the data needed for those services. Details are provided below:

  • Stripe: Payment processing. Stripe collects your payment details, billing address, and shipping address during checkout. See Stripe's Privacy Policy
  • Prodigi: Print fulfilment and shipping. We share your name, shipping address, email, and phone number with Prodigi to print and deliver physical orders. See Prodigi's Privacy Policy
  • Strava: Activity data access via OAuth. See Strava's Privacy Policy
  • Mapbox: Map data and styling for topographic posters. See Mapbox's Privacy Policy
  • Google Analytics: Website analytics and traffic analysis. Google Analytics uses cookies to collect information about how visitors use our site (with consent where required). See Google's Privacy Policy
  • NextAuth.js: Authentication and session management

11. Data Retention

We retain your personal data only for as long as necessary to fulfil the purposes for which it was collected. Specific retention periods are as follows:

  • Order and transaction data (including name, address, email): Retained for up to 6 years after the date of the transaction, as required by UK tax and accounting regulations (HMRC).
  • Strava OAuth tokens: Stored in encrypted form while your connection is active. Automatically deauthorised and deleted after a period of inactivity.
  • Activity data (routes, statistics): Retained as part of your order record for the duration of the order data retention period.
  • Analytics data (Google Analytics): Subject to Google's data retention settings. We configure a 14-month retention period.
  • Log files: Retained for up to 90 days for security and debugging purposes.

12. International Data Transfers

Some of our third-party service providers process data outside the United Kingdom:

  • Stripe processes payment data in the United States and other jurisdictions, relying on Standard Contractual Clauses (SCCs) and their compliance with data protection standards.
  • Google Analytics processes data in the United States, relying on SCCs and Google's data processing terms.
  • Prodigi may fulfil orders from production facilities in various countries. Prodigi acts as a data processor on our behalf and is contractually bound to protect your data.

Where personal data is transferred outside the UK, we ensure appropriate safeguards are in place, including Standard Contractual Clauses approved by the UK Information Commissioner's Office, or transfers to countries with an adequacy decision.

13. Data Security

We implement appropriate technical and organisational measures to protect your personal information against unauthorised access, alteration, disclosure, or destruction. This includes encryption of sensitive data at rest (such as Strava tokens), secure HTTPS connections, and access controls. However, no method of transmission over the Internet or electronic storage is 100% secure, and we cannot guarantee absolute security.

14. Children's Privacy

Our service is not intended for children under the age of 18. We do not knowingly collect personal information from children under 18. If you are a parent or guardian and believe your child has provided us with personal information, please contact us immediately at contact@zewstudio.com.

15. Online Privacy Policy Only

Our Privacy Policy applies only to our online activities and is valid for visitors to our website with regards to the information that they shared and/or collect in Zew Studio. This policy is not applicable to any information collected offline or via channels other than this website.

16. Consent

This Privacy Policy explains how we collect, use, and protect personal data when you use our website. Where consent is required, we will ask for it separately.

If you have any questions about this Privacy Policy, please contact us at contact@zewstudio.com.
