Privacy Policy

Last updated: August 12, 2026

1. Introduction

AdFlint ("we," "our," or "us") operates the AdFlint platform at adflint.com. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our advertising management service.

2. Information We Collect

Account Information

When you create an account, we collect your name, email address, and authentication credentials. We use secure third-party authentication providers (such as Google OAuth) to manage sign-in.

Campaign Data

We collect the personal and business data needed to provide AdFlint. When you create advertising campaigns, this includes the information you provide including business name, ad copy, target audience parameters, budget allocations, and creative assets.

Images and videos that must be fetched by Google or Meta are stored at non-guessable public media URLs. Anyone who obtains one of those URLs can access the file, so you should not upload confidential material as ad media. For supported text briefs, AdFlint extracts the text and deletes the temporary public source file after processing. PDF briefs are not accepted unless private document storage is available.

Lead Contact Information

When someone submits an AdFlint-hosted lead form or a connected Meta instant form, we store the contact details they consented to provide so the advertiser can follow up. Contact fields are encrypted at rest and are only revealed through authenticated, account-scoped requests. We separately retain one-way hashes and campaign attribution data for measurement and connected-platform conversion feedback.

Payment Information

Payment processing is handled by Stripe. We do not store your credit card numbers or banking details on our servers. Stripe collects and processes your payment information in accordance with their own privacy policy.

Identity Verification

To prevent fraud and abuse, we may require identity verification for certain accounts, performed by Stripe Identity. Any government-issued ID, selfie, or Social Security information you provide is collected and held by Stripe, not by AdFlint. We receive only a verification result and minimal confirmation data — we never receive or store your SSN, ID number, or images. Stripe processes this information under its own privacy policy.

Usage Data

We automatically collect certain information when you use our platform, including IP address, browser type, device information, pages visited, and timestamps. This data helps us improve our service and troubleshoot issues. We use PostHog for product analytics and consented session replay. Replay inputs, text, and element attributes are masked, and analytics and replay stop when consent is declined or a supported browser privacy signal is present.

Advertising & Conversion Tracking

To measure ad performance, our first-party pixel captures advertising click identifiers (such as Google's gclid, Meta's fbclid, Microsoft's msclkid, TikTok's ttclid, X's twclid, and Pinterest click IDs), an approximate location derived from your IP address, and a randomly generated visitor ID stored in your browser. We use this to attribute conversions and improve campaign optimization, and we may share conversion data (including click identifiers) with connected advertising platforms to measure and optimize ad delivery. You can decline this non-essential tracking via the cookie banner, and we honor a Global Privacy Control (GPC) or “Do Not Track” signal automatically.

3. How We Use Your Information

  • To create, manage, and optimize advertising campaigns on your behalf across currently available platforms (Google Ads and Meta), with additional integrations as they become available
  • To process your subscription payments and manage billing
  • To provide campaign performance analytics and reporting
  • To use AI-powered features to generate ad copy, optimize targeting, and improve campaign performance
  • To communicate with you about your account, campaigns, and platform updates
  • To detect and prevent fraud or abuse of our services
  • To comply with legal obligations and enforce our terms of service

4. Advertising Platform Data

AdFlint acts as an intermediary between you and advertising platforms. When we run campaigns on your behalf, the advertising platforms (currently Google and Meta) may collect data in accordance with their own privacy policies. We share the minimum information necessary to create and manage your campaigns, such as ad copy, targeting parameters, and budget details.

5. Google User Data

When you connect a Google Ads account, AdFlint requests your permission through Google OAuth and accesses data in that account on your behalf. This section describes exactly what we access, why, and how it is handled.

Scopes we request and why

  • https://www.googleapis.com/auth/adwords — required to read the campaigns, ad groups, keywords, ads, budgets, conversion actions, performance metrics, and Google-generated recommendations in the Google Ads account you authorize, and to create, update, pause, and resume campaigns, budgets, and ads in that same account. AdFlint is an ad-management product, so read-only access is not sufficient — launching and optimizing campaigns requires write access.
  • https://www.googleapis.com/auth/datamanager — required to upload offline conversion events you send us (for example, a sale that closed after an ad click) back to your Google Ads account through the Google Data Manager API, so that Google can attribute and optimize for conversions that happen off your website.

How we store and protect it

OAuth access and refresh tokens are encrypted at rest on our servers and are used only to make API calls to Google on your behalf. Google Ads data we retrieve (campaign structure and performance metrics) is stored to render your dashboard and reporting. No AdFlint employee accesses your Google user data except where you have given explicit consent (for example, to troubleshoot a support request), where it is necessary for security purposes, or where required by law.

Retention and deletion

You can disconnect a Google Ads account at any time from Settings, which immediately revokes AdFlint's access and deletes the stored tokens. Google Ads data previously retrieved for that account is deleted within 30 days of disconnection, except where we are required to retain records for legal, accounting, or fraud-prevention purposes. You may also request deletion of your account and all associated data at privacy@adflint.com.

Limited Use

AdFlint's use and transfer to any other app of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements. Specifically, we do not sell Google user data, we do not use it for advertising purposes other than operating the advertising campaigns you have asked us to run in your own account, we do not use it to train generalized artificial intelligence or machine learning models, and we do not transfer it to third parties except as necessary to provide or improve the features you use, to comply with applicable law, or as part of a merger or acquisition with prior notice to you.

6. AI Processing

AdFlint uses artificial intelligence to generate ad copy, suggest targeting parameters, and optimize campaign performance. Your campaign data may be processed by AI models to provide these features. Depending on the feature, AdFlint uses API services from OpenAI, Anthropic, and Microsoft Azure. We do not use your data, including any data obtained from Google APIs, to train generalized artificial intelligence or machine learning models. AI processing is used solely to provide and improve the features you are actively using.

If you opt into Google ad-strength auto-optimization, we may send the campaign's Google ad text, platform ad-strength feedback, and related campaign context to our AI service provider to generate revised headlines and descriptions. This opt-in feature is capped at two attempts per campaign. This transfer is limited to providing that feature to you under the provider's business/API data terms. The data is not sold or used by AdFlint for advertising outside your own account.

7. Data Sharing

We may share your information with:

  • Advertising Platforms: Google Ads and Meta to run campaigns on your behalf. Additional platforms may be added as integrations become available.
  • Payment & Identity Processors: Stripe for payment processing and identity verification
  • AI and Media Service Providers: OpenAI, Anthropic, and Microsoft Azure to power campaign analysis, copy generation, and supported media generation
  • Analytics Provider: PostHog to help us understand and improve the service, subject to the consent controls described above
  • Hosting and Storage Providers: Vercel and our database and infrastructure providers to host AdFlint and store account, campaign, and creative data
  • Legal Requirements: When required by law, court order, or governmental authority

We do not sell your personal information for money. We do share advertising and conversion data with Google and Meta to measure and optimize ad delivery, which some privacy laws (such as California's CPRA) classify as “sharing” for cross-context behavioral advertising. You can opt out of this at any time via the cookie banner or by enabling a Global Privacy Control (GPC) signal in your browser.

8. Data Security

We implement industry-standard security measures to protect your data, including encryption in transit (TLS/SSL), encrypted data at rest, and secure authentication mechanisms. However, no method of transmission over the internet is 100% secure, and we cannot guarantee absolute security.

OAuth tokens are encrypted before database storage. Public creative media is limited to files that advertising platforms must retrieve; access to the rest of the application data requires authenticated, authorized server requests.

Lead email addresses, phone numbers, names, company information, and locations are encrypted at rest. Lead notifications do not include contact information; advertisers must sign in to view it.

9. Data Retention

We retain account data while your account is active and campaign data and analytics for up to 24 months after a campaign ends. Supported text-brief source files are deleted immediately after text extraction. Removing a creative attachment removes its stored file when one exists. Limited transaction, security, and fraud-prevention records may be retained where legally required. You may request deletion of your account and associated data at any time by contacting us or following the steps on our Data Deletion page.

10. Your Rights

Depending on your jurisdiction, you may have the right to:

  • Access the personal data we hold about you
  • Request correction of inaccurate data
  • Request deletion of your data
  • Object to or restrict processing of your data
  • Request data portability
  • Withdraw consent at any time

To exercise any of these rights, contact us at the email address below or use the instructions on our Data Deletion page.

11. Cookies

We use essential cookies required for authentication and platform functionality. We also use non-essential cookies and browser storage for analytics and advertising/conversion measurement (including the click identifiers and visitor ID described above). You can decline the non-essential ones via our cookie banner — and we honor a Global Privacy Control (GPC) or “Do Not Track” browser signal automatically — or manage cookies through your browser settings.

12. Children's Privacy

AdFlint is not intended for use by individuals under the age of 18. We do not knowingly collect personal information from children. If we become aware that we have collected data from a child, we will take steps to delete it promptly.

13. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of any material changes by posting the updated policy on our platform with a revised "Last updated" date. Your continued use of AdFlint after changes are posted constitutes acceptance of the updated policy.
