1. What this Privacy Notice is about
Sealivo provides a “verified media kit” for newsletter creators and a discovery/outreach workflow for brands. Creators can connect an email/newsletter provider via API key, Sealivo fetches aggregate metrics (such as subscriber count and average open rate where available), and creators may publish a public trust page and an embeddable badge. Brands can browse creators, save shortlists, and send sponsorship requests; creators can accept/decline and optionally reveal contact details upon acceptance.
This Privacy Notice describes how we process personal data in connection with these features. We may provide additional “just-in-time” notices for specific situations.
2. Controller and how to contact us
Sealivo is the controller for the processing described in this Privacy Notice.

3. What data we process (categories and examples)
We process different categories of personal data depending on how you use Sealivo. “Personal data” means any information relating to an identified or identifiable person.
3.1 Technical data (website/app usage and infrastructure)
When you visit or use the website or Service, we may process technical data such as:
- IP address (infrastructure logs and security systems)
- device/browser information (user agent, language, approximate location derived from IP)
- timestamps, pages visited, referrer URLs
- identifiers stored in cookies or similar technologies (for example authentication session cookies)
Technical data is primarily used to operate the Service, secure it, and understand usage patterns.
3.2 Registration and account data (authentication)
If you create an account or sign in, we process:
- email address
- authentication/session identifiers and tokens (handled by Supabase Auth and stored as cookies)
- login method (for example email/password, magic link, Google OAuth)
- account identifiers (for example a user UUID)
- account role and access flags (creator vs brand; subscription access)
Passwords (where used) are processed by Supabase Auth. Sealivo does not store raw passwords.
3.3 Master data (profiles and business identity)
Depending on your role, we process profile data such as:
Creators
- username, display name, avatar URL
- niche, newsletter URL, about text, audience country
- sponsor contact fields you choose to provide (such as sponsor email and/or sponsor URL)
- whether your profile is public
Brands
- company name, website, industry
3.4 Newsletter provider connection data (credentials and metadata)
Creators may connect supported newsletter providers (for example Kit (formerly ConvertKit), Beehiiv, MailerLite, Brevo, Mailchimp). If you connect a provider, we process:
- provider name and configuration metadata (for example publication/list identifiers)
- API credentials you provide (stored encrypted at rest)
- operational metadata such as last fetched time and error information (if a fetch fails)
Important: Sealivo is designed to store aggregate metrics (see next section) rather than subscriber-level personal data. However, when calling provider APIs, subscriber-level data may be processed in transit in the provider response even if we do not store it. We work to avoid storing or logging subscriber-level data unless necessary for troubleshooting.
3.5 Verified metrics (snapshots)
We store verification snapshots such as:
- subscriber count
- average open rate (where available)
- verification timestamp and provider reference
These snapshots may be used to power creator dashboards, public pages, the public leaderboard, and badge images.
3.6 Communications data (support and marketplace messages)
We process communication data such as:
- messages sent through the marketplace workflow (brand → creator sponsorship requests)
- responses and status (accepted/declined) and timestamps
- if accepted: contact details the creator provides (for example contact email and/or URL), which are then revealed to the requesting brand
Support channels (depending on configuration) may include:
- support email correspondence
- support chat conversations (Crisp) if enabled
3.7 Billing and contract data (payments and subscriptions)
If you subscribe to a paid plan (if applicable), we process billing-related data such as:
- Stripe customer identifiers and subscription/access status stored in our database
- invoices, payment status and payment method information processed by Stripe
Payments (including payment method details and tax information, if any) are processed by Stripe. Sealivo does not store full payment card details on its servers.
3.8 Leads / marketing contact data
If you submit your email through our lead form (if used), we process:
- email address
- timestamp and metadata related to the submission
3.9 Other data you submit
Certain fields in Sealivo allow free-form text (for example profile “about” text and sponsorship request messages). You control what you submit. If you include sensitive data (for example health or political information), we may process it as part of providing the Service, but the Service is not intended for collecting sensitive data.

6. Legal bases (where applicable)
Depending on applicable law and context, we may process personal data based on:
- Contract / pre-contractual steps (for example, providing the Service, billing, marketplace workflows)
- Legitimate interests (for example, security, preventing abuse, improving reliability and product development)
- Consent (for example, certain marketing communications where required; optional support chat; optional analytics where required by cookie laws)
- Legal obligations (for example, tax/accounting retention where applicable)
Where we rely on consent, you may withdraw your consent at any time with effect for the future.
7. Profiling and automated decision-making
7.1 Profiling
We may analyze usage and behavior in the Service (for example what pages are used and how features are used) to improve the Service, detect abuse, and understand performance. This may be performed through analytics tooling and internal service metrics.
We do not use personal data for “data sale” or behavioral advertising as a business model.
7.2 Automated decisions
The Service includes automated processes such as:
- subscription access control (for example enabling/disabling features based on Stripe subscription status)
- leaderboard ordering based on verification metrics
These processes are designed for service functionality and are not intended to produce “significant” legal effects about you in the sense of fully automated decision-making under certain laws. If this changes, we will update this Privacy Notice.
8. Sharing and recipients
We do not sell your personal data.
We share personal data with recipients where necessary to operate the Service:
8.1 Service providers (processors)
We use service providers that process personal data on our behalf, such as:
- Supabase (authentication and database)
- Vercel (hosting and infrastructure; may include logs and analytics)
- Stripe (payments and subscription management)
- Plausible and Vercel Analytics (analytics; depending on configuration)
- Crisp (support chat) if enabled
8.2 Newsletter provider integrations (independent services)
If you connect a newsletter provider, we send your credentials to that provider to authenticate API requests and retrieve metrics from that provider. These providers typically act as independent controllers for their own services.
8.3 Other users (marketplace disclosure)
Brands and creators may see data needed to run sponsorship requests (for example message content and statuses). If a creator accepts a request, the creator’s provided contact details are revealed to the requesting brand.
8.4 Authorities and legal disclosures
We may disclose personal data to authorities, courts or other parties if required by law or to protect our rights.
9. Public profiles, leaderboard and badge disclosure
Sealivo includes features that intentionally publish certain creator information and verification metrics (for example on a creator public page, the public leaderboard, and badge images).
If you enable a public profile, your public profile data and selected verified metrics may be accessible to anyone on the internet. This may include sponsor contact fields you choose to publish. You control what you choose to publish, and you can disable public visibility through your settings.
10. International data transfers
Our service providers and integration partners may process personal data in countries outside your country of residence (including outside Switzerland and the EEA). Where required, we rely on appropriate safeguards (such as contractual protections) to support such transfers.
Note: Internet communications and cloud services may route data through multiple jurisdictions even if endpoints are in the same country.
11. Retention and deletion
We retain personal data for as long as necessary to provide the Service, comply with legal obligations, resolve disputes, and enforce agreements.
Retention depends on the data category and purpose. Examples:
- Account and profile data: for the duration of your account, and for a reasonable period after deletion to handle obligations and disputes.
- Provider connection data (encrypted credentials): while the connection is active; removed when you disconnect or delete your account (subject to backups).
- Verified metrics snapshots: retained to provide verification history; may remain visible for public profiles until removed or the profile is made private.
- Marketplace messages: retained to provide the marketplace workflow, prevent abuse, and support dispute handling.
- Billing records: retained as required by applicable tax/accounting laws and for audit purposes.
- Technical logs and security data: retained for security, debugging and abuse prevention, typically for limited periods.
If you request deletion, some data may still be retained where legally required or necessary for legitimate interests (for example billing records or abuse-prevention logs).
12. Security
We use appropriate technical and organizational measures designed to protect personal data. Examples evidenced in our architecture include:
- encryption of newsletter provider credentials at rest (application-side encryption)
- access controls and row-level policies in our database to limit access to data
- HTTPS for data in transit
- authentication and session management with Supabase Auth
- protections around sensitive endpoints (for example cron routes and signed email relay requests if enabled)
No security system is perfect. We continuously improve security controls as the Service evolves.
13. Cookies, analytics and similar technologies
13.1 Necessary cookies (authentication and core functionality)
Sealivo uses necessary cookies to maintain authentication sessions and provide core functionality (for example staying signed in). If you disable these cookies, the Service may not function properly.
13.2 Analytics
Sealivo uses:
- Plausible (via
next-plausible) - Vercel Analytics
to measure usage and improve performance. Depending on configuration and applicable law, analytics may use cookies or similar technologies.
13.3 Support chat (optional)
If enabled, Sealivo may use Crisp for customer support chat. Crisp may store identifiers using cookies or local storage to provide chat functionality and may associate the chat session with a user identifier.
13.4 Your choices
You can typically control cookies through your browser settings and delete cookies at any time. If you disable certain cookies, parts of the Service may not function properly.
14. Your rights
Depending on applicable law, you may have rights such as:
- access to your personal data
- correction of inaccurate data
- deletion of data (subject to exceptions)
- restriction of processing
- data portability (where applicable)
- objection to certain processing
- withdrawal of consent (where we rely on consent)
