Privacy Policy

Sling holds your church's weekly numbers and your own notes about them. That data belongs to your church. We use it to give you readings of your week, and for nothing else. We do not sell it, we do not share it with other churches, and your observations are never used to train AI models. Sling reads the church as a whole; it never keeps a file on a person.

When you use Sling, we collect:

• Account details. Names, email addresses, and (if you opt in to the Monday text) phone numbers for the pastors and staff on your team.
• Church metrics. Weekly attendance counts, giving totals, group participation, and the other numbers you log. These are totals, not individual giving records.
• Pastoral observations. The notes you write about your week. We treat these as sensitive: they may mention people in your congregation by name and describe personal circumstances. They are scoped to your church, visible only to your team, and never shared.
• Survey responses. Answers your congregation submits through Sling surveys.
• Technical basics. Log and device data needed to keep the service running and secure.

We use your data to run Sling for your church: producing your weekly readings, answering the questions you ask, sending the Monday prompt, and keeping your account working. We also use aggregate, de-identified usage data to improve the product.

We do not sell your data. We do not share one church's data with another. We do not use your data for advertising.

Sling uses AI (Anthropic's Claude models) to read your numbers alongside your notes and produce your weekly reading, and Voyage AI to make your notes searchable. Your data is sent to these providers only to process your requests. Your observations are never used to train AI models. Our agreements with our AI providers prohibit training on your content.

Sling runs on a small set of service providers, each used for one job:

• Vercel: application hosting
• Neon: database
• Clerk: sign-in and account management
• Twilio: text messages (the Sunday and Monday texts)
• Resend: email (your welcome note and team invites)
• Inngest: scheduling the weekly texts and background jobs
• Sentry: error monitoring so we can fix what breaks
• Anthropic: AI processing of your readings and questions
• Voyage AI: embeddings that make your notes searchable

Each provider only receives the data it needs to do its job, under contracts that limit how they can use it.

If you opt in by providing your mobile number, Sling sends you at most two texts a week. On your service day in the evening, and only if nothing has been logged for the week yet, it asks for the count. On Monday morning it sends one question: your count reflected back, then “What do you remember about the room?” You reply with a number or a sentence. Reply STOP at any time to cancel. Reply HELP for help. Message and data rates may apply. Consent to receive texts is not a condition of using Sling. Carriers are not liable for delayed or undelivered messages.

Mobile information will not be shared with third parties or affiliates for marketing or promotional purposes.

We keep your church's data for as long as your account is active; the whole point of Sling is memory that compounds. If you close your account, we delete your church's data within 30 days, except where the law requires us to keep certain records longer.

You can also ask us to delete specific data, or everything, at any time. Email hello@sling.church and we will take care of it.

Your data is encrypted in transit and at rest. Access inside Sling is scoped to your church: your team sees your data and no one else's. Our own access is limited to what is needed to operate and support the service.

Sling is a tool for church staff and is not directed at children. We do not knowingly collect personal information from anyone under 13.

If anything here is unclear, or you want to exercise any of the rights above, write to us at hello@sling.church. A person reads that inbox.
