Cookie Policy

Last updated: May 26, 2026

This Cookie Policy explains how Trendosity (“we”, “our”) uses cookies and similar technologies on trendosity.com and our mobile apps. It works alongside our Privacy Statement and our Terms of Use.

1. What are cookies?

Cookies are small text files that a website places on your device when you visit. They let us recognise your browser on your next visit, keep you signed in, remember your preferences, and understand how the site is used. We also use similar technologies — local storage, session storage, web beacons, and SDK identifiers in our mobile apps — and we group all of these under “cookies” in this policy.

2. Categories of cookies we may use

We group cookies into four categories. You can accept all, reject the non-essential ones, or toggle each category in the cookie banner that appears on your first visit and at any time afterwards from your account settings.

Essential

Required for the site to work. Keep you signed in, prevent fraud, remember your consent choices, route requests securely.

Functional

Remember your preferences across visits — last city you browsed, your color theme, whether you've dismissed a tip — to make the experience feel like yours.

— not currently set —
We do not store functional cookies today. If we add any, they will be listed here and require your consent.

Performance / Analytics

Anonymous, aggregated insight into how the site is used so we know what works and what doesn't. We don't use this to identify you individually.

— not currently set —
We do not run third-party analytics today. If we add Google Analytics, Plausible, or similar, they will be listed here, set only with your consent, and respect Do-Not-Track / GPC signals.

Marketing / Advertising

Lets us surface relevant offers tied to recommendations — for example, a "Book on Booking.com" button for a hotel a friend recommended, or a deep link to a restaurant's OpenTable page, or a discount on a product. We may receive a referral fee. We may also use this to measure whether those offers are useful. Off by default — only set if you explicitly opt in via the banner.

— not currently set —
We do not place advertising cookies today. If and when we do (booking partners, affiliate networks), they will be listed here, set only with your explicit consent, and you can withdraw consent at any time.

3. Third parties that may set cookies on our behalf

We work with a small set of processors. Each is contractually bound to use cookies only for the purposes we authorise. We list every one here and update this list when it changes.
  • · Supabase — sets the authentication session cookie that keeps you signed in.
  • · Vercel — sets a session cookie for our hosting platform; it does not see your account data.
  • · Google Maps Platform — when you view a map or a Places autocomplete, Google may set its own cookies subject to Google's Privacy Policy.
  • · Resend — emails only; no cookies in your browser.
  • · Anthropic — server-to-server only; no cookies in your browser.
  • · Future analytics or affiliate / advertising partners — none today. When we add them, they will appear in the relevant category above and the cookie banner will request your consent before any cookie is set.

4. Your choices

You can manage cookies in several ways:

  • · Cookie banner. On your first visit, accept all, reject non-essential, or toggle each category. You can re-open the banner anytime by clearing the tr_cookies cookie or visiting your Settings.
  • · Browser controls. Most browsers let you block or delete cookies in their privacy settings. See Chrome, Safari, Firefox, Edge. Blocking essential cookies will sign you out and prevent the site from working.
  • · Global Privacy Control (GPC). We honor the browser-level GPC signal automatically — if your browser sends it, we treat you as having opted out of non-essential cookies and of sale/share, and we don't show the banner.
  • · Do Not Sell or Share My Personal Information. California (CCPA/CPRA) residents can opt out separately at any time at /do-not-sell.
  • · Mobile app SDK identifiers. If we ship native apps, you can reset your device's advertising identifier in iOS / Android settings.

5. Cross-border transfers

Some of our processors operate in jurisdictions outside the EEA / UK / Switzerland. We rely on Standard Contractual Clauses (SCCs) and equivalent transfer mechanisms to protect your data when it moves across borders. See our Privacy Statement § Processors for the full list and basis.

6. Updates to this policy

We may update this Cookie Policy when we add or remove a cookie, change a processor, or adjust how we work with marketing partners. Material changes will be flagged in the cookie banner so you have the chance to review your choices.
