Sprigwise Privacy Policy

Last updated: September 23, 2026

This policy explains what information Sprigwise collects, why, and who it goes to. It covers the website at www.sprigwise.com and the Sprigwise mobile apps. Sprigwise is run by Sprigwise LLC in Port Wentworth, Georgia. Questions or requests: support@sprigwise.com.

1. Accounts are optional

You can use all of Sprigwise with no account at all. Most of what you do stays on your phone or computer.

If you choose to create an account (email and password), we use it for one thing: keeping your My Garden list the same on every device you log in from. An account stores your email address, a securely hashed password, and your saved plant list (plant IDs, status and planting date). Photos, yard photos and answers are not uploaded. If you tick "Remember this device", a sign-in token is kept on that device for up to 90 days so you do not have to log in again; untick it on a shared device and you are logged out when the browser closes. Accounts are run for us by Supabase (see Service providers).

2. What stays on your device

• The yard photo you add in Analyze My Yard. The light check runs on your device and the photo is never uploaded.
• Your ZIP code. Your hardiness zone, broad region and typical soil are looked up on your device.
• Your answers about sun, soil, water and space.
• My Garden, the plants you save, their status, and the photo log for each plant.
• Your Yard Code backup, which only leaves your device if you copy or share it yourself.
• In the iPhone app, the weekly garden check-in reminder. It is scheduled on your phone and nothing is sent to us.

You can erase this information by removing plants in My Garden, clearing the site data in your browser, or deleting the app.

3. What leaves your device, and when

• Plant advice. When you tap How would this do in MY yard?, we send the plant you picked plus your zone, broad region, sun, soil, drainage, watering and space answers to our server.
• Photo check-ins. When you snap a photo in How's it doing? or tap Check this photo, we send that one photo (resized, with its location data removed) plus your zone, broad region, sun, soil, drainage and watering answers to our server.
• Who writes the advice. Our server passes these requests to Anthropic, the company that makes the Claude AI model, to write the answer. Anthropic handles them under its own terms and privacy policy. Sprigwise does not store the photo or your answers after the reply is sent. The iPhone app asks for your permission before it sends the first request.
• Yard count. The first time you set a saved plant to a status other than Planning, your device sends a random ID one time, so we can count how many yards are tracking their plants. It is not tied to your name or email.
• Usage counts. When a yard analysis finishes, your device sends a simple count with no personal information.
• Newsletter (website only). If you join the email list, your email address is sent through FormSubmit, an email relay service, to our inbox. Every email lets you unsubscribe.
• Premium (website only). Premium is bought on the website through Stripe, which collects your card details directly. We receive the purchase details Stripe shares with us, such as your email and payment status, but never your full card number. To restore Premium on a new device, the website asks for your checkout email and the last 4 digits of the card you paid with and checks them with Stripe. Your device then keeps a Premium token that is checked with our server from time to time.
• Analytics (website only). The website counts page views with GoatCounter, which uses no cookies. It records the page address, the referring site, browser and screen size, and a country-level location worked out from your IP address. The iPhone app has no analytics.
• Nurseries near you. This opens a Google Maps search for your ZIP code. On the website, if you allow it, your browser's location is used for that search instead. The iPhone app never uses your device location. Google handles these searches under its own privacy policy.
• Store links. Links to retailers and other sites take you to those sites, which have their own privacy policies. Our retailer links don't add tracking codes.

4. Service providers

We use these companies to run Sprigwise: GitHub Pages (hosts the website), Vercel (runs our server), Anthropic (writes plant advice), Supabase (optional accounts and garden sync), Stripe (website payments), FormSubmit (email list relay) and GoatCounter (website page counts). Like most online services, the website host and our server provider keep short-lived technical logs, such as IP addresses and request times, to operate and protect their systems.

We do not sell your personal information, and we do not share it for targeted advertising. We may disclose information if the law requires it or to protect the rights and safety of our users or Sprigwise.

5. How long we keep information

• Newsletter addresses: until you unsubscribe or ask us to delete them.
• Premium purchase records: for as long as your subscription is active, and afterward as long as tax and accounting rules require.
• Yard counts and usage counts: kept only in our server provider's logs, without names or emails.
• Advice requests: Sprigwise does not store them after the reply is sent.

6. Deleting your data

Information on your device is deleted when you remove it in the app, clear your browser's site data, or delete the app. If you made an account, open My Garden and choose "Delete my account": your email, password and synced garden are removed from our systems immediately, and the copy on your device stays until you clear it. To delete anything Sprigwise holds, such as your newsletter address or Premium records, email support@sprigwise.com with the email address you used. We confirm and complete verified requests within 30 days. We may keep records the law requires us to keep.

7. Your privacy rights

Depending on where you live, including California and the European Economic Area and United Kingdom, you may have the right to know what information we hold about you, to get a copy, to correct it, to delete it, and to object to or limit how we use it. We do not sell or share personal information, and we will not treat you differently for using these rights. To make a request, email support@sprigwise.com. You may also complain to your local data protection authority.

8. Security

Information that leaves your device travels over encrypted connections (HTTPS), and we limit who can access our systems. No method of storage or transmission is completely secure.

9. Children

Sprigwise is not directed to children under 13, and we do not knowingly collect information from them. If you believe a child has sent us information, email us and we will delete it.

10. Changes to this policy

If we change this policy, we will post the new version here with a new "Last updated" date.
