Privacy policy
Last updated: 4 June 2026
CardShareAI ("we", "us") runs cardshare.ai and related services that let you create group greeting cards, collect messages from others, and share finished cards. This policy explains what information we collect, why we use it, and the choices you have.
Who this applies to
It covers people who create an account, build or manage cards, and anyone who opens a contribute or view link. Contributors can add a note without signing up; we still process the content they submit and basic technical data needed to run the service.
Information we collect
- Account information: Such as your email address and sign-in details when you register or use Google or GitHub login.
- Card content: Recipient and sender names, headlines, messages, uploaded photos, GIFs, layout choices, and contributions from people who sign your card.
- Link and session data: Contributor links are unlisted but not secret; anyone with the link can view or sign the card depending on the page. We may store edit tokens in your browser so you can update your own contribution from the same device.
- Usage and diagnostics: Pages visited, feature use, and similar product analytics (for example via PostHog) to understand what works and fix problems.
- AI processing: Prompts and context you provide for headlines, messages, or cover art, plus the outputs our AI partners return. Do not include sensitive personal data you do not want processed for generation.
- Slack integration: If you install our Slack app, we receive workspace and user identifiers needed to run slash commands and deliver card links in Slack.
How we use information
We use data to:
- Host cards, authenticate users, and deliver email you request
- Generate and refine AI copy and images at your direction
- Display cards to people you share links with
- Improve reliability, security, and the product experience
- Comply with law and respond to valid requests
We do not sell your personal information.
How we share information
We use trusted service providers for hosting, databases, authentication, email, analytics, AI, and (if you use it) Slack. They process data on our instructions to operate CardShareAI. When you share a card link, you control who receives it. We do not publish cards in a public directory.
Retention
Card data is kept while your card exists in our systems. You can delete cards from your dashboard. If you want your account removed, email us. We may keep limited logs and backups for security, fraud prevention, and legal obligations, then delete them when no longer needed.
Your choices
- Review and edit card content before sending or sharing links
- Delete cards you manage from the dashboard
- Ask us for access, correction, or deletion of account-related data at hello@cardshare.ai
- Use browser controls or opt-out tools where available for analytics cookies
Security
We use industry-standard measures such as encrypted connections and access controls. No online service is perfectly secure; please use a strong password and treat share links like private invitations.
Children
CardShareAI is not directed at children under 13, and we do not knowingly collect their personal information. Contact us if you believe we have done so and we will take appropriate steps.
International users
We may process and store information in countries where we or our providers operate. By using the service, you understand your data may be transferred to those locations, with safeguards where required by law.
Changes
We may update this policy from time to time. We will post the new date at the top of this page. Continued use after changes means you accept the updated policy.
