Last updated: 28 April 2026

HymnDeck is operated by Juan Miguel Sanchez, a sole trader based in England, United Kingdom. For the purposes of UK data protection law, Juan Miguel Sanchez is the controller of personal data processed through HymnDeck.
You can contact us about privacy or support matters at support@hymndeck.app.
2. Information We Collect
We collect and process the following kinds of information when you use HymnDeck:
- Account data: your email address, authentication identifier, organisation membership, and account settings.
- Content data: song sheets, service text, lyrics, slide content, deck names, generated presentation content, design settings, uploaded design assets, and related material you provide or create in the service.
- Google Drive import data: files or Google Docs content you choose to import so HymnDeck can extract text and create slides.
- Billing data: if paid plans are offered and you choose to subscribe, billing identifiers, subscription status, plan, renewal dates, and related billing metadata.
- Technical data: authentication cookies, device and browser information, IP address, request metadata, and operational metadata processed by our hosting, database, infrastructure, and API providers.
3. Google Drive and Imported Content
HymnDeck's use and transfer to any other app of information received from Google APIs will adhere to Google API Services User Data Policy, including the Limited Use requirements.
- Scope of access: we request access to
https://www.googleapis.com/auth/drive.file. This allows HymnDeck to view and manage only files you explicitly select with the Google Drive Picker. We do not have access to view or manage your whole Google Drive. - Import use: selected files are used to extract text for slide generation and related HymnDeck features.
- Raw file storage: raw Google Drive files are not retained by HymnDeck after import.
- Extracted and generated text: raw extracted text may be sent to our AI provider to parse and format it. The changed output text, saved decks, song sheets, and related presentation data may be stored in your HymnDeck account.
- Access revocation: you can revoke HymnDeck's Google access from your Google account permissions.
4. AI Processing and Service Providers
HymnDeck uses AI to parse, format, and transform worship presentation content. When you use these features, relevant content may be sent to OpenRouter and processed by the underlying model provider selected for the request, currently Google Gemini 3.0 Flash via OpenRouter.
We also use service providers to run HymnDeck, including:
- Google Firebase: authentication and account identity.
- OpenRouter and Google Gemini: AI parsing and formatting.
- Vercel: frontend hosting.
- Google Cloud Run: API hosting.
- Google Cloud Storage: storage for design and presentation assets.
- Neon: database hosting.
- Lemon Squeezy: billing and subscription management if paid plans are used.
We do not intentionally keep application-level logs of your content, but our infrastructure and service providers may process operational logs and metadata for security, reliability, debugging, abuse prevention, and billing.
5. How We Use Information
We use personal data where we have a lawful basis to do so, including:
- Contract: to provide accounts, import content, generate presentations, save decks and song sheets, and manage subscriptions.
- Legitimate interests: to secure the service, prevent abuse, debug issues, improve reliability, and support users.
- Legal obligation: to keep records required for tax, accounting, fraud prevention, or legal compliance.
HymnDeck is designed for worship presentation content. You should not upload unnecessary personal or sensitive information about identifiable individuals. If you choose to upload such information, you are responsible for ensuring you have a lawful basis to do so.
6. Retention and Deletion
- Account data: kept while your account is active.
- Saved decks, song sheets, and generated output: kept while your account is active unless deleted earlier.
- Google Drive raw files: not retained after import.
- Imported raw text: not retained as a separate raw import unless it becomes part of saved output in your HymnDeck account.
- Billing records: if paid plans are used, kept for as long as required for tax, accounting, and legal record keeping.
HymnDeck currently handles account deletion requests manually. To request deletion of your account and associated saved content, contact support@hymndeck.app.
7. Cookies and Authentication
HymnDeck uses cookies and similar technologies for authentication, session routing, account access, security, and basic operation of the service. These cookies are used to keep you signed in and to route you correctly through the app.
8. Sharing and International Transfers
We share personal data with service providers only as needed to operate HymnDeck, provide AI processing, host the service, authenticate users, store saved content, process billing, provide support, comply with law, or protect the service.
Our providers may process data outside the United Kingdom. Where this happens, we rely on the provider's transfer safeguards and contractual commitments.
9. Your Rights
Depending on the circumstances, you may have rights to access, correct, delete, restrict, object to, or receive a copy of your personal data. You can make a request by emailing support@hymndeck.app.
You also have the right to complain to the UK Information Commissioner's Office at ico.org.uk/make-a-complaint.
10. Security
We use reasonable technical and organisational measures to protect personal data. No online service can be guaranteed to be completely secure, and you are responsible for keeping your account credentials safe.
11. Children
HymnDeck is not intended for children under 13. If you believe a child has provided personal data through HymnDeck, contact us so we can review and delete it where appropriate.
12. Changes and Contact
We may update this Privacy Policy as the service changes. If you have questions about this policy or how HymnDeck handles data, contact support@hymndeck.app.
