1. Who we are
This policy describes how Nanostack (“we”, “us”) handles personal information when you visit https://nanostack.io, use our marketing AI software or related services, or connect third-party accounts such as Meta (Facebook) products for advertising, analytics, or authentication.
Questions: info@nanostack.io.
2. Information we collect
Depending on how you use our services, we may collect:
- Account and contact data: name, email, company, billing details, and support messages you send us.
- Product usage data: device or browser type, approximate location, pages or features used, diagnostics, and performance logs to operate and improve the service.
- Content you submit: campaign briefs, creative assets, audience definitions, prompts, and other materials you upload or generate through the product.
- Third-party integrations: when you connect Meta (Facebook) or other platforms, we may receive identifiers, tokens, and data those platforms make available through their APIs (for example ad account IDs, campaign metrics, or profile information permitted by your connection and their terms).
3. How we use information
We use personal information to:
- Provide, secure, and improve our marketing AI features;
- Authenticate you and manage your account;
- Process payments and fulfill contracts;
- Communicate about the service, security, and lawful updates;
- Comply with law and enforce our terms.
4. Legal bases (where applicable)
If regional law requires a legal basis, we rely on performance of a contract, legitimate interests (such as security and product improvement, balanced against your rights), consent where required (for example certain cookies or marketing communications), and legal obligation.
5. Sharing and subprocessors
We share information with service providers that help us host, analyze, secure, or deliver the service (for example cloud hosting, analytics, email delivery, and payment processors). They may only use data as instructed by us. We may also disclose information if required by law or to protect rights and safety.
6. Retention
We keep information for as long as needed to provide the service, meet legal and accounting obligations, and resolve disputes. Retention periods vary by data type; contact us to learn more about a specific category.
7. Security
We use administrative, technical, and organizational measures designed to protect personal information. No method of transmission or storage is completely secure.
8. International transfers
If we transfer personal information across borders, we use appropriate safeguards where required by applicable law.
9. Your rights
Depending on where you live, you may have rights to access, correct, delete, or restrict processing of your personal information, or to object to certain processing or to data portability. You may also have the right to lodge a complaint with a supervisory authority. To exercise rights, email info@nanostack.io. We may need to verify your request.
10. Meta (Facebook) and platform data
If you use features that connect to Meta technologies, Meta’s own privacy policy and terms apply to their services. We process platform data only as described here and as permitted by your authorization and applicable platform rules.
11. Cookies
We and our partners may use cookies or similar technologies for essential operation, preferences, analytics, and (where allowed) marketing. You can control cookies through your browser settings and any cookie banner we provide.
12. Children
Our services are not directed to children under 16, and we do not knowingly collect their personal information.
