Summary of key points
The headline answers, in plain language. Each point links to the full treatment below.
What we process. Account identifiers (email, display name, OAuth subject ID), usage telemetry (IP, device, browser, referrer), and payment metadata if you purchase a paid plan. We do not process sensitive personal information.
From third parties. We do not collect personal information from third parties beyond what you authorize via Google OAuth at sign-in.
Why we process it. To provide and improve the Services, communicate with you, prevent fraud, and comply with law. We process your information only when we have a valid legal reason to do so.
Who we share it with. A small set of named processors (Stripe for payments, Anthropic for AI assistance, Google for sign-in and analytics). Never sold.
How we keep it safe. Industry-standard transport encryption, encrypted refresh-token storage with quarterly key rotation, OWASP-aligned secure-coding practice. No system is 100% secure; we do not guarantee otherwise.
Your rights. Depending on where you live, you may request access, correction, a copy, or deletion of your personal information. Contact [email protected] or submit a data subject access request.
§ 1
What information we collect
Personal information you disclose to us
We collect personal information that you voluntarily provide when you register for the Services, contact us, or participate in features. The categories we collect:
- names and display names
- email addresses
- phone numbers (only if you provide them)
- mailing or billing addresses (only if you provide them)
- usernames and contact preferences
- contact and authentication data (Google OAuth subject ID)
Sensitive information. We do not process sensitive personal information (e.g., race, ethnicity, sexual orientation, religion, biometric data, government IDs).
Payment data. If you purchase a paid plan we collect what is necessary to process payment. All payment data is handled and stored by Stripe; we do not store full card numbers on our servers. See stripe.com/privacy.
Social-login data. We use Google OAuth to sign users in. When you authenticate, Google sends us the profile fields you authorize: email, display name, profile picture URL, and a stable subject ID. We do not request or receive any other Google account data. Our use of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.
All personal information that you provide must be true, complete, and accurate, and you must notify us of any changes.
Information collected automatically
When you use the Services, certain information is collected automatically. This information does not on its own reveal your identity but may include:
- Log and usage data — IP address, browser type and settings, language, referring URL, device name, country, location, request timestamps, pages and features used.
- Device data — device and application identifiers, OS, system configuration, ISP / mobile carrier.
We also collect information through cookies and similar technologies. See our Cookie Notice.
§ 2
How we process your information
We process your personal information for the following purposes:
- To provide and maintain accounts. Create and authenticate accounts, keep them in working order.
- To deliver the Services. Pricing tools, agentic comparables, alerts, and any feature you enable.
- To respond to user inquiries. Customer support, bug reports, account questions.
- To send administrative information. Service announcements, security notices, policy updates.
- To prevent fraud and abuse. Detect and respond to suspicious activity, protect Card Pulse and its users.
- To comply with legal obligations. Respond to lawful requests, exercise or defend legal rights.
- To save or protect a person’s vital interest. For example, to prevent harm.
We process your information only when we have a valid legal reason to do so, and only with your prior explicit consent for purposes outside this list.
§ 3
Legal bases we rely on
The General Data Protection Regulation (GDPR) and UK GDPR require us to explain the valid legal bases for processing. We rely on:
- Consent — when you have given us permission. You can withdraw consent at any time.
- Performance of a contract — to provide the Services you have signed up for.
- Legal obligations — when compliance with law requires it.
- Vital interests— when necessary to protect anyone’s safety.
If you are located in Canada, we may process your information with your express or implied consent. In limited cases (fraud detection, investigations, public-interest disclosures, etc.) Canadian law permits processing without consent; we follow those rules.
§ 4
When and with whom we share information
We may share your personal information in these specific situations:
- Business transfers. In connection with a merger, sale of assets, financing, or acquisition of all or a portion of our business.
- Service providers. Stripe (payments), Anthropic (AI), Google (sign-in and analytics), our hosting and database providers — each bound by a written contract.
- External pricing sources. When the agentic pricing engine pulls comparables from third-party APIs (eBay, PriceCharting, GoCollect, etc.), we send only the search terms necessary to identify the card; we do not send your account information to these sources.
- Compliance with law. When required by court order, subpoena, regulatory inquiry, or to defend legal claims.
We do not sell or share personal information for cross-context behavioral advertising.
§ 5
Cookies and tracking
We use cookies and similar technologies to maintain session security, remember preferences, and assist with basic site functions. We may permit Google Analytics to collect usage information on our behalf. Specifics — including how to opt out — live in our Cookie Notice.
§ 6
AI products
Cardpulse offers tools powered by artificial intelligence, including agentic price recommendations and decision cards backed by Anthropic (Claude). When you use these tools, your input and the resulting output are processed by the underlying AI provider under their terms and ours. We do not sell your inputs or outputs and we do not use them to train any third-party model. See Anthropic’s privacy policy for their handling.
§ 7
Social logins
Cardpulse currently supports sign-in via Google OAuth only. When you choose to sign in with Google, Google sends us the profile fields described in §1: email, display name, profile picture URL, and a stable subject ID. We use this information solely to create and authenticate your account. We do not receive your Google password and we do not request access to your Gmail, Drive, Calendar, or any other Google service.
We recommend reviewing Google’s privacy notice to understand how they handle your information.
§ 8
How long we keep your information
We keep personal information only as long as necessary for the purposes outlined in this notice, unless a longer retention period is required or permitted by law (tax, accounting, fraud-prevention). Where there is no ongoing legitimate business need to process your information, we will either delete it or anonymize it. If immediate deletion is not possible (for example, because the data is in backup archives), we will securely store and isolate it from further processing until deletion is possible.
§ 9
How we keep your information safe
We use appropriate organizational and technical safeguards: HTTPS in transit, encrypted refresh-token storage with quarterly key rotation, restricted internal access on a need-to-know basis, and continuous monitoring for unusual activity. No electronic transmission or storage system can be guaranteed 100% secure, so we cannot promise your information will never be improperly accessed.
§ 10
Information from minors
Cardpulse is not directed to children, and we do not knowingly collect data from anyone under 18 years of age (or the equivalent age of majority in your jurisdiction). If we learn that we have collected personal information from a person under that age, we will delete it and deactivate the associated account. If you believe we may have collected information from a minor, please contact [email protected].
§ 11
Your privacy rights
Depending on your jurisdiction, you have rights including:
- request access to your personal information
- request correction or deletion
- request a portable copy
- restrict or object to processing
- withdraw consent at any time
You can review or update your account from your dashboard, or contact us at [email protected]. We will consider and act upon any request consistent with applicable law. If you are in the EEA or UK and you believe we are processing your personal information unlawfully, you have the right to complain to your Member State data protection authority or the UK ICO.
§ 12
Do-Not-Track signals
Most browsers offer a Do-Not-Track (“DNT”) setting. There is no industry or legal standard for honoring DNT signals, so we do not currently respond to them. If a uniform standard is adopted in the future, we will update this notice to reflect our practice.
§ 13
