What Data We Collect

We collect minimal data to provide a good experience:

  • Timezone preference — stored locally in your browser (localStorage) to display event times in your timezone
  • Cookie consent preference — stored locally to remember your cookie choice
  • Sidebar state — stored locally to remember if you collapsed the sidebar
  • PWA prompt preference — stored locally to remember if you dismissed the install prompt

All of the above are stored in your browser's localStorage only. No personal data is sent to or stored on our servers.

Lawful Basis for Processing

Under UK GDPR, we must have a lawful basis for processing any personal data. As we only store preference data locally on your device via localStorage, this falls under:

  • Legitimate Interests (Article 6(1)(f)) — storing your preferences locally is necessary to provide you with a functional and personalised experience. This data never leaves your device and poses no risk to your rights and freedoms.

We do not process personal data on our servers. No accounts, registrations, or personal identifiers are collected.

Cookies & Similar Technologies

This site uses localStorage to save your preferences (timezone, language, accessibility, tool progress) and does not set any tracking cookies of its own. Third-party services embedded on the site may set their own cookies for advertising and analytics:

  • Google Analytics 4 — aggregated site usage statistics. Sets the standard _ga family of cookies.
  • Microsoft Clarity — anonymised session replays and heatmaps to help us diagnose UX issues. Sets _clck, _clsk and Microsoft domain cookies (MUID, SM). Clarity masks form inputs by default and respects the browser's Do Not Track signal.
  • Google Fonts — does not set cookies but causes your IP to be briefly logged when font files load.

A full list of cookies (names, purposes, retention periods) and the opt-out links for each service is available on our Cookie Policy.

Advertising (Google AdSense)

This site uses Google AdSense to display advertisements. Google AdSense may use cookies and similar technologies (including the DoubleClick cookie, the IDE cookie, and other Google advertising cookies) to:

  • Serve ads based on your prior visits to this site and other sites on the web.
  • Measure ad performance (impressions, clicks, conversions) for advertisers.
  • Detect fraudulent or invalid clicks and impressions.
  • Optionally personalise the ads you see, based on Google's profile of your interests.

Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to this site and/or other sites on the Internet. You can:

Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to this website or other websites. For more information about how Google uses any data it collects through this site, please review Google's policy on how it uses information from sites that use its services.

Visitors in the EU, UK, and other regions covered by data-protection regulations: Personalised ads require your consent. Where required, ad personalisation is disabled by default until you accept via the cookie notice on the bottom of every page.

Third-Party Links

This site contains links to external websites including:

  • BD Digital Creations (bddc.co.uk)
  • Discord (discord.gg)
  • Google Forms (docs.google.com)
  • Ko-fi, GitHub, PayPal
  • Sponsor/affiliate links (Hostinger, Proton VPN)

We are not responsible for the privacy practices of these external sites. We encourage you to read their privacy policies.

Affiliate Links & Sponsors

Some links on this site are affiliate links. If you make a purchase through these links, we may earn a small commission at no extra cost to you. This helps support the development of this free tool.

Sponsored content is clearly labelled on the site.

Analytics

We use Google Analytics 4 and Microsoft Clarity to understand how the site is used so we can improve it. Both are configured in their least-intrusive modes:

  • Google Analytics 4 anonymises IP addresses before storage and does not share data for advertising by default.
  • Microsoft Clarity masks form inputs, respects the browser Do Not Track signal, and does not combine data with any personally identifiable information.

Neither service is used for marketing profiles or cross-site tracking by us. You can opt out of both individually — see the Cookie Policy for links.

Your Rights Under UK GDPR

Under the UK General Data Protection Regulation, you have the following rights in relation to your personal data:

  • Right of Access — you have the right to request a copy of any personal data we hold about you. As we do not collect or store personal data on our servers, there is no data to provide.
  • Right to Rectification — you have the right to request correction of inaccurate personal data.
  • Right to Erasure — you have the right to request deletion of your personal data. You can clear all locally stored preferences at any time by clearing your browser's site data.
  • Right to Restrict Processing — you have the right to request that we limit how we use your data.
  • Right to Data Portability — you have the right to receive your data in a portable format.
  • Right to Object — you have the right to object to the processing of your personal data.

Since we do not collect personal data on our servers, most of these rights are satisfied by default. To exercise any of these rights, please contact us at hello@bddc.co.uk.

Data Retention

We do not retain any data on our servers. Data we save to your browser's localStorage (preferences, tool progress, consent choice) remains until you clear your site data. Data collected by third-party services has its own retention periods — see the Cookie Policy for each service.

International Data Transfers

The third-party services we embed (Google Analytics, Google Fonts, Microsoft Clarity) may transfer limited technical data (such as your IP address and browser type) to servers outside the United Kingdom.

Google LLC and Microsoft Corporation participate in the UK Extension to the EU–US Data Privacy Framework, which the UK government recognises as providing an adequate level of data protection. See the Google Privacy Policy and Microsoft Privacy Statement for full details.

Children's Privacy

This site does not knowingly collect any personal information from children under 13. As we do not collect personal data from any users, this applies to all visitors regardless of age. If you believe a child has provided us with personal data, please contact us and we will take steps to remove it.

Changes to This Policy

We may update this privacy policy from time to time. Any changes will be reflected on this page with an updated "Last updated" date. We encourage you to review this page periodically.

If you are unhappy with how we have handled your data, you have the right to lodge a complaint with the Information Commissioner's Office (ICO), the UK's supervisory authority for data protection:
