ATDb (“The AdTech Database,” “we,” “us,” or “our”) is operated by Jon Holm as a personal project. This Privacy Policy describes how we collect, use, and share information when you use theatdb.com (the “Service”).
Account Information. When you create an account, we collect your email address and any display name you provide. You may use a pseudonym. Accounts are managed through Supabase Auth.
Contribution Data. If you submit edits or additions to the database, we store your contribution history, including the content of each edit, timestamps, edit summaries, and source URLs you provide. Your display name is associated with your contributions and may be visible to other users in edit histories. We also track your trust level, which is based on the quantity and quality of your approved contributions.
Usage Data. We automatically collect information about how you interact with the Service, including pages visited, features used, and referring URLs.
Analytics. We use Google Analytics 4 (via Google Tag Manager) and PostHog for analytics. Google Analytics collects aggregated usage data such as pages visited, session duration, device type, browser, approximate geographic location, and referring sources. PostHog provides product analytics and session replay, recording anonymized browsing sessions to help us understand navigation patterns. Both services use consent-based activation — analytics cookies are only set after you grant consent via our cookie banner. If you decline, no analytics cookies are placed on your device.
Cookies. We use essential cookies for authentication (Supabase session cookies) and analytics cookies (Google Analytics and PostHog, with your consent). When you first visit ATDb, a consent banner lets you accept or reject analytics cookies. You can change your preference at any time via the “Cookie Settings” link in the footer. See our Cookie Policy for details.
We use the information we collect to:
The following information may be publicly visible to other users of the Service:
Your email address is never publicly displayed. It is used only for account authentication, transactional emails (password resets, verification), and notification emails that you have explicitly opted into.
Transactional emails (account verification, password resets, security alerts) are sent as needed to operate your account. These do not require separate opt-in and cannot be disabled while your account is active.
All other emails are opt-in only. We will never send you notification or marketing emails unless you explicitly enable them in your account settings. Every notification type (edit reviews, trust level changes, daily digests, administrative reports) is disabled by default and must be individually enabled by you. You may disable any notification at any time.
We do not sell your personal information. We share information only with the following service providers, who process data on our behalf:
We may also disclose information if required by law or to protect our rights.
If you are in the European Economic Area (EEA) or the United Kingdom, we process your personal data under the following legal bases:
If you are in the EEA or the United Kingdom, you have the following rights regarding your personal data:
To exercise any of these rights, contact us at admin@theatdb.com. We will respond within 30 days.
If you are a California resident, the California Consumer Privacy Act (CCPA) and California Privacy Rights Act (CPRA) provide you with specific rights regarding your personal information:
Categories of Information Collected. In the preceding 12 months, we may have collected: identifiers (email address, display name), internet activity information (browsing history on our site, search queries, contribution history), and geolocation data (approximate location via analytics).
To exercise any of these rights, contact us at admin@theatdb.com. We will verify your identity before processing your request and respond within 45 days.
ATDb is operated from the United States. Your personal data may be transferred to and processed in the US and other countries where our service providers operate, including:
Where data is transferred outside the EEA or UK, our service providers rely on Standard Contractual Clauses (SCCs), the EU-US Data Privacy Framework, or other approved transfer mechanisms to ensure adequate protection of your personal data.
We retain your account information for as long as your account is active. Usage and analytics data is retained in accordance with our service providers' retention policies (Google Analytics retains data for 14 months by default; PostHog retains data according to your plan settings).
Contribution data: Approved contributions become part of the collaborative database. If you delete your account, we will remove your email address and personal identifiers. Previously approved contributions may be retained in anonymized form (attributed to “[deleted user]”) to preserve the integrity of the database and its edit history. This is similar to how collaborative platforms like Wikipedia handle contribution history.
You may request deletion of your account and personal data at any time by contacting us at admin@theatdb.com.
We implement reasonable technical and organizational measures to protect your information, including encrypted connections (HTTPS), secure authentication via Supabase, and access controls. However, no method of transmission or storage is 100% secure, and we cannot guarantee absolute security.
The Service is not directed at children under 13. We do not knowingly collect personal information from children under 13. If you believe a child under 13 has provided us with personal information, please contact us and we will delete it.
Some browsers send a “Do Not Track” signal. There is no industry standard for how websites should respond to this signal. However, ATDb provides a direct control mechanism: our cookie consent banner lets you explicitly accept or reject analytics tracking, and you can change your preference at any time via the “Cookie Settings” link in the footer.
We may update this Privacy Policy from time to time. If we make material changes, we will update the effective date at the top of this page. Your continued use of the Service after changes are posted constitutes your acceptance of the revised policy.
