Cookie Policy

Last updated: June 1, 2026

1. What Are Cookies

Cookies are small text files placed on your device by a website you visit. They are widely used to make websites work efficiently, remember your preferences, and provide information to site owners. Cookies do not contain executable code and cannot access other data on your device.

2. Types of Cookies We Use

Strictly Necessary

Always active

These cookies are essential for the app-column website and developer portal to function. They enable core features such as session authentication, secure API key management, and CSRF protection. You cannot opt out of these cookies.

  • session_id — maintains your authenticated developer session
  • csrf_token — protects against cross-site request forgery
  • cookie_consent — stores your cookie preferences

Analytics

Requires consent

We use analytics cookies to understand how developers interact with our documentation, dashboard, and marketing pages. This helps us improve the developer experience and identify where users encounter friction.

  • Google Analytics 4 — page views, session duration, traffic sources (anonymised IP)
  • Segment — product analytics, feature adoption, funnel analysis
  • Hotjar — anonymised heatmaps and session recordings (no API credential data)

Marketing & Targeting

Requires consent

Marketing cookies allow us to show relevant advertising about app-column on third-party platforms and measure campaign performance. We do not sell your data to advertisers.

  • LinkedIn Insight Tag — campaign attribution for developer and fintech audiences
  • Google Ads — conversion tracking and remarketing

3. Why We Use Cookies

  • Keep you securely signed in to the developer dashboard and API console
  • Remember your documentation preferences (language, theme, sidebar state)
  • Measure which API guides and tutorials are most useful to developers
  • Attribute sign-ups to the correct marketing channel so we can invest in relevant content
  • Detect and prevent fraudulent access to the platform

4. Third-Party Cookies

Some cookies on our site are set by third-party services we embed — including Google, LinkedIn, Segment, and Hotjar. These parties operate under their own privacy policies and may use the data collected for their own purposes. We contractually require these vendors to process data only as instructed by us and in compliance with applicable law. Links to their privacy policies:

5. How to Manage & Disable Cookies

You can control non-essential cookies in several ways:

  • Cookie banner — when you first visit app-column you are presented with a consent banner. You can accept all, reject non-essential, or configure individual categories.
  • Browser settings — all modern browsers allow you to block or delete cookies. Note that disabling strictly necessary cookies will impair dashboard functionality.
  • Opt-out tools — use the Google Analytics opt-out browser add-on or Hotjar opt-out page.
  • Do Not Track — we honour the DNT browser header by disabling analytics and marketing tracking.

6. Consent

By clicking "Accept all" on our cookie banner, you consent to the placement of analytics and marketing cookies as described above. You may withdraw consent at any time by clearing your cookies and revisiting the banner, or by contacting us at [email protected]. Withdrawing consent does not affect the lawfulness of any processing carried out before withdrawal.

7. Changes to This Policy

We may update this Cookie Policy to reflect changes in our technology or applicable law. When we make material changes, we will update the "Last updated" date at the top of this page and, where appropriate, notify you via email or an in-dashboard notice. Your continued use of app-column after any changes constitutes acceptance of the revised policy.
