Privacy policy.

Marketiq is a price-comparison service for European markets, offered as both the marketiq.me website and the Marketiq Android app on Google Play. We operate as an independent developer.

On the website (marketiq.me):

• Anonymous session ID — a random identifier from Firebase Anonymous Auth so we can call our search APIs. No name, email, or personal data attached.
• Search queries — only kept in your browser to render results; not stored on our servers.
• Standard server logs — IP, user-agent, and request URL, retained 30 days, for security and abuse prevention.

On the app:

• Account data — email and username when you register.
• Usage data — search queries, price alerts, country preference.
• Push token — only if you enable price alerts.
• Camera — used only for barcode scanning; no images stored or transmitted.

We use only essential cookies needed for the site to function. The cookie banner you see on first visit lets you choose between “Essential only” and “Accept”. If you pick Essential only, nothing below this paragraph runs.

If you click Accept, we enable two privacy-respecting tools to help us run the site:

• PostHog (EU host). Anonymous product analytics — page views, button clicks, search counts. Hosted in the EU; your IP is never stored. Used to understand which features actually help users. We do not link this to any account.
• Sentry (EU host). Error monitoring. When the site crashes we receive the technical stack trace plus a masked replay of the page (all text hidden, all inputs hidden, all images blocked). Used to fix bugs faster. We do not see your search queries, your typed input, or any image you viewed.

If we later introduce advertising (e.g. Google AdSense), we will show a separate banner asking you to choose between personalised ads, non-personalised ads, or no ads — before any tracking cookies are set. EU users always have the choice.

• To return price-comparison search results.
• To send price-drop notifications you requested (app only).
• To remember your language and country preferences.
• To enforce free / Pro usage limits (app only).

• Firebase (Google)— anonymous authentication, database, push notifications. Privacy policy.
• eBay Partner Network — product search and affiliate links. Privacy policy.
• Awin— affiliate product links across European retailers. Privacy policy.
• AliExpress— affiliate product links. Privacy policy.
• Stripe— payment processing for Pro subscriptions (app only). Privacy policy.
• Firebase Hosting (Google) — website hosting and CDN for marketiq.me (Firebase project marketiq-3d1b7). Anonymised request logs only. Covered by the Firebase Privacy policy.

Marketiq earns a commission when you purchase through links on the website or in the app. This does not affect the price you pay. We display affiliate links from eBay, Awin, AliExpress, and other retail networks.

All user data is stored on Google Firebase servers in Europe (europe-west1) for GDPR compliance. We do not sell your data to third parties. We do not transfer data outside the EU.

If you are in the European Union you have the right to access, correct, or delete your data. In the app, delete your account from Profile → Delete Account — this also wipes any anonymous web session linked to your account. For other requests, contact us at the email below.

Marketiq requires users to be 16 years or older, in accordance with GDPR Article 8.
