Effective 9 November 2026.
This policy explains what information Stone Portrait ("we", "us") collects when you use stoneportrait.com, how we use it, and the choices you have. Stone Portrait is a service for monument dealers and etchers. It turns a family's photo into a portrait file for a memorial. Questions go to hello@stoneportrait.com.
The short version
- Your photos are private to your account. We don't sell them, share them for advertising, or use them to train AI models.
- Photos are stored with Google Cloud (Firebase Storage) in the United States.
- AI edits run on GPUs at Modal in the United States. Photos are processed there only for the time it takes to run the edit.
- Payments are handled by Stripe. We never see your card number.
- We don't use advertising trackers.
- You can delete a portrait at any time, and its photos are deleted with it.
What we collect
- Account information. Your email address and the sign-in data needed to log you in. Accounts are managed through Firebase Authentication, a Google service.
- Photos and portraits. The photos you upload, the edited versions the service creates, and your settings for each portrait, such as size, shape, laser preset and tone.
- Proof activity. When someone uses a proof link to approve a portrait, we record the approval, the time, and any name or note they enter.
- Billing information. Your plan, credits, and payment status. Stripe processes the payment. We receive limited details from Stripe, such as a customer ID and whether a payment succeeded, but never your full card number.
- Technical information. Basic logs such as IP address, browser type and the time of requests. We use these to keep the service running and secure.
- Messages. Anything you send us by email, such as support requests.
How we use it
- To provide the service: store your portraits, run the edits you ask for, create files and proofs, and show proof links.
- To manage your account, credits and subscription, and to process payments.
- To answer support requests and send messages about your account, such as receipts and important service changes.
- To keep the service secure, prevent abuse, and fix problems.
- To meet legal obligations, such as keeping billing records.
We do not sell personal information. We do not use your photos or portraits to train AI models, and we do not show them to anyone outside your account except through proof links you choose to share.
Where your photos are stored and processed
Photos and edited versions are stored in Google Cloud through Firebase Storage, in the United States. They are private to your account. Other dealers cannot see them.
When you run an AI edit or an upscale, the photo is sent to GPUs run by Modal, in the United States. It is processed there transiently, only for the time needed to run the edit, and the result is returned to your account. Photos are not used to train any AI model.
Proof links
A proof link is a long, unguessable web address. Anyone who has the link can open the proof and see the portrait on it. Share it only with the family members who need it. If a link is shared further than you intended, delete the portrait or contact us, and the proof will no longer be available.
Service providers
We use a small number of providers to run Stone Portrait. They process data on our behalf and only to provide their service to us.
| Provider | What they do | Location |
|---|---|---|
| Google (Firebase Authentication, Firebase Storage, Google Cloud) | Sign-in, storage of photos and portraits, hosting | United States |
| Modal | GPUs that run AI edits and upscaling | United States |
| Stripe | Payments and subscriptions | United States and other countries where Stripe operates |
We may also disclose information if the law requires it, to protect the rights and safety of our users or others, or as part of a sale or merger of the business. In that case, this policy continues to apply to your information.
Cookies and tracking
We use only the cookies and browser storage needed to sign you in and keep the service working, such as remembering your session. We do not use advertising trackers or sell data to ad networks.
Photos of families and people who have died
Dealers upload photos on behalf of the families they serve. The dealer is responsible for having the family's permission to use those photos with Stone Portrait. If you are a family member and have a question about a photo, please contact the dealer you worked with, or write to us at hello@stoneportrait.com and we will help.
How long we keep it
- Portraits and their photos are kept until you delete them, or until your account is deleted.
- When you delete a portrait, its photos and edited versions are deleted, and its proof link stops working.
- If you ask us to delete your account, we delete your account information and portraits. We keep billing records for as long as the law requires.
Your choices and rights
You can view, download and delete your portraits in your account at any time. You can ask us for a copy of your personal information, ask us to correct it, or ask us to delete your account, by writing to hello@stoneportrait.com. Depending on where you live, you may have further rights under local law. We will respond to requests within a reasonable time and as the law requires.
Security
Photos are stored privately and access is limited to your account. Connections to the service are encrypted. No system is perfectly secure, so please keep your sign-in details safe and tell us right away if you think your account has been misused.
Children
Stone Portrait is a business service and is not meant for children. We do not knowingly collect personal information from anyone under 16 as a user of the service.
Changes to this policy
We may update this policy as the service changes. We will post the new version on this page with a new effective date. If a change is significant, we will also tell you by email or in the app.
