Privacy Policy
Last updated 16 October 2026
This policy explains what personal data SEQN collects, why, who it's shared with and your rights. the company that operates SEQN is the controller of your personal data. Contact us at support@seqn.app.
What we collect
- Account: your email address, and your name and picture if you sign in with Google.
- Your content: what you upload or write (videos, photos, audio, voice recordings, scripts, logos) and the projects SEQN makes from it.
- Channel details: the YouTube channels you enter, and the public information SEQN reads about them (titles, recent videos, view counts).
- Payments: your plan, billing status and history. Card details go straight to Stripe; we never see or store them.
- Usage: which AI features you used and the credits they cost, and technical logs (such as errors and IP addresses) that keep SEQN working and secure.
Why we use it
- To provide SEQN: sign you in, store and process your projects, make your videos and take payment (our contract with you).
- To keep SEQN secure, fix problems and prevent abuse (our legitimate interests).
- To meet legal duties, such as tax and accounting records (legal obligation).
- To email you about your account, payments and important changes. We don't send marketing without your consent, and you can opt out at any time.
We don't sell your personal data, and we don't use your content to train AI models.
Who we share it with
Only the providers needed to run SEQN, each under a contract that protects your data:
- Supabase: signing in.
- Stripe: payments, tax and fraud prevention.
- Railway: hosting the service and storing your projects.
- AI providers, only when you use a feature that needs them: Anthropic (research and writing), OpenAI (images and thumbnails), ElevenLabs (voices). They receive what that feature needs (for example your script, or the photos you chose for a thumbnail) and don't use it to train their models.
- Email delivery: sending sign-in links and account messages.
- Backup storage: encrypted copies of projects and account records, if backups are kept off-site.
Research reads public web pages, Wikipedia and news indexes; it sends them your search topic, not your personal data. Some providers are outside the UK and EU; where that happens, transfers are protected by approved safeguards such as the UK International Data Transfer Addendum or EU Standard Contractual Clauses.
YouTube
SEQN uses YouTube API Services to read public channel and video information and to show YouTube videos. Google's Privacy Policy applies to what Google receives, and using these features means you agree to the YouTube Terms of Service. SEQN only reads public information and doesn't access your YouTube account. If you ever connect a Google account to SEQN, you can remove its access at Google's security settings.
Cookies and local storage
SEQN uses only the cookies it needs to work: to keep you signed in, and (while SEQN is in testing) to remember the access password. Your browser also stores small preferences such as layout choices. There are no advertising or tracking cookies.
How long we keep it
- Your projects and uploads: until you delete them, or your account.
- Your account: until you ask us to delete it. We then delete your data within 30 days, apart from copies in backups (removed within a further 14 days) and records we must keep by law, such as invoices (usually 6 years).
- Technical logs: up to 90 days.
Your rights
Under UK and EU data protection law you can ask to see your data, correct it, delete it, receive a copy, limit or object to how we use it, and withdraw consent where we rely on it. Email support@seqn.app and we'll reply within a month. If you're unhappy with how we handle your data, you can complain to the Information Commissioner's Office (ico.org.uk) or your local data protection authority.
Security
Data is encrypted in transit; access to it is limited to what's needed to run SEQN, and projects are backed up nightly. No service is perfectly secure; if a breach affects you, we'll tell you as the law requires.
Children
SEQN isn't meant for children under 13, and we don't knowingly collect their data.
Changes
We'll post changes here, and tell you by email or in SEQN about important ones.
