Sena (“Sena”, “we”, “us”, or “our”) operates the websites at heysena.ai and app.heysena.ai and the related content tools (the “Service”). The Service connects to your X (formerly Twitter) account, learns how you write from your own posts, and helps you draft, edit, and schedule content in your voice.
This Privacy Policy explains what information we collect, why we collect it, who we share it with, and the choices and rights you have. It applies to your use of the Service. For data-protection questions you can reach us at privacy@heysena.ai.
When you connect X, you authorize us through X’s official sign-in (OAuth) to access certain data. We never receive or store your X password. Depending on the permissions you grant, this may include:
You can disconnect your X account at any time from your settings, which revokes our ongoing access.
Subscriptions and trials are billed through our payment processor, Stripe. Stripe collects and processes your card or payment-method details directly. We do not receive or store full card numbers; we retain only limited billing records such as your plan, subscription status, the last four digits and card brand, and billing history needed to manage your account and prevent fraud.
We use the information above to:
Where required by law, our legal bases for processing are: performance of our contract with you (providing the Service), your consent (e.g. optional marketing and connecting your X account), our legitimate interests (securing and improving the Service), and compliance with legal obligations.
Sena uses third-party artificial-intelligence providers to analyze your posts and generate content. Your posts and the rough ideas you enter are sent to these providers solely to build your voice profile and to produce drafts for you.
We keep your information for as long as your account is active and as needed to provide the Service. If you delete your account, we delete or anonymize your personal data within a reasonable period, except where we must retain certain records (for example, billing and tax records, or to resolve disputes and enforce our agreements). You can request deletion at any time — see “Your rights”.
Depending on where you live (including under the EU/UK GDPR and the California CCPA/CPRA), you may have the right to:
We do not sell or “share” personal information for cross-context behavioral advertising as those terms are defined under California law. To exercise any right, email privacy@heysena.ai. We will respond within the time required by applicable law and will not discriminate against you for exercising your rights. You also have the right to lodge a complaint with your local data-protection authority.
We and our sub-processors may process your information in countries other than your own, including the United States. Where we transfer personal data internationally, we rely on appropriate safeguards such as the European Commission’s Standard Contractual Clauses (or equivalent mechanisms) to protect your information.
We use technical and organizational measures — including encryption in transit, access controls, and OAuth-based connections that avoid handling your X password — to protect your information. No method of transmission or storage is completely secure, so we cannot guarantee absolute security. If we become aware of a breach affecting your personal data, we will notify you and the relevant authorities as required by law.
The Service is not directed to anyone under 18, and we do not knowingly collect personal information from children. If you believe a child has provided us with personal information, contact us at privacy@heysena.ai and we will delete it.
We may update this Privacy Policy from time to time. If we make material changes, we will update the “Last updated” date above and, where appropriate, notify you by email or in the Service. Your continued use of the Service after the changes take effect means you accept the updated policy.
