Consumer Health Data Privacy Policy

Applies to: the Alpha-Gal Wise™ app and alphagalwise.com, operated by WILLIAMS TECHNOLOGIES LLC.
Version: Rev E. Effective date: October 19, 2026.

This policy covers “consumer health data” under the Washington My Health My Data Act, Nevada Senate Bill 370, and Connecticut law. It supplements our Privacy Policy. Consumer health data means information that is linked or reasonably linkable to you and that identifies your past, present, or future health status. Because the app is about alpha-gal syndrome, simply using it could suggest you have a health condition, so we treat the data below as consumer health data.

Consumer health data we collect

• Anonymous ingredient reports (only if you turn them on): the product barcode, public product name, brand, and ingredient text, the ingredient words the app didn't recognize, the label source, app version, platform, and date.
• Label photos you Share (only for each photo you Share): the cropped photo with location and camera data removed, the scrubbed text read from it, the barcode, the date, app version and platform, the consent version, and a random withdrawal code.
• Network information: when the app opens, it checks our server for settings, so our hosting provider logs your IP address for security and delivery and keeps it for up to 7 days. Nothing else is sent unless you choose to.
• Support emails: your email address and anything you tell us, which may include health information.

We do not collect your triggers, allergens, symptoms, reactions, diagnosis, scan history, saved photos that you don't Share, or your location. We don't use geofencing. When you scan a product, the app looks up the barcode directly with Open Food Facts, which may return a record from its sister projects Open Beauty Facts or Open Products Facts. We don't receive that lookup, and we don't keep a list of products you scan.

Sources of consumer health data

We get it only from you: what you choose to send from the app (reports and shared photos), technical details the app adds when you send them (app version and platform), our hosting provider's security and delivery logs (including the IP address logged when the app checks for settings at launch), and emails you send us. We don't buy consumer health data or get it from other companies.

How we use consumer health data

• To find and add ingredients the app didn't recognize and improve matching.
• To review photos you Share and, if they pass review, add them to Open Food Facts, Open Beauty Facts, or Open Products Facts.
• To answer your questions and requests.
• To keep our systems secure, prevent abuse, and comply with the law.

We don't use it for advertising, marketing, or profiling, and we don't try to re-identify anyone from de-identified reports or photos.

Consumer health data we share, and with whom

We share consumer health data only with service providers that process it for us under contract and only on our instructions:

• Supabase (database and storage hosting, in the United States) and its network provider Cloudflare: reports, shared photos, and delivery logs.
• ImprovMX (email forwarding) and Google Gmail (email hosting) handle messages sent to support@alphagalwise.com.

One exception you control: a label photo you Share, with its text and barcode, is submitted to Open Food Facts (openfoodfacts.org), Open Beauty Facts (openbeautyfacts.org) for cosmetics and personal care products, or Open Products Facts (openproductsfacts.org) for household products, all run by the same independent nonprofit in France, if it passes review. It is then public. Your per-photo Share tap is your consent to this sharing. We do not send ingredient reports to any of them automatically.

We may also disclose data if the law requires it. The app does not show ads, and we never share consumer health data with advertisers.

Consent and withdrawing consent

• Ingredient reports: collected only after you choose “Send anonymous reports” or turn on Settings → Help improve ingredient matching. Turn it off anytime to stop future reports.
• Label photos: stored on your device. We collect a photo only if you separately consent by tapping Share. We share it with Open Food Facts, Open Beauty Facts, or Open Products Facts only as part of that same consent, which you give for each photo separately from any other consent. Withdraw any photo not yet published in Settings → Label photos.

Saying no, or withdrawing consent, never limits any other app feature. Withdrawal stops future collection and deletes unpublished photos; it can't undo a photo already published on Open Food Facts, Open Beauty Facts, or Open Products Facts.

How long we keep it

• Ingredient reports: stored de-identified, and deleted or reduced to aggregate statistics within 90 days.
• Shared photos: stored de-identified and deleted from our systems right after review, or automatically within 30 days of upload if not reviewed.
• Hosting logs with IP addresses: up to 7 days.
• Support emails: only as long as needed to help you.

We do not sell consumer health data

We do not sell consumer health data, and we will not do so without your signed, written authorization as the law requires. Submitting a photo you Share to Open Food Facts, Open Beauty Facts, or Open Products Facts involves no payment or other value.

Your rights and how to exercise them

If you live in Washington, Nevada, or Connecticut (and in some other states), you have the right to:

• Access: confirm whether we collect, share, or sell your consumer health data, and get a copy of it;
• Know who receives it: get a list of the third parties and service providers we share it with, and how to contact them;
• Delete: have us delete it, and have our service providers delete it;
• Withdraw consent: stop our collection and sharing at any time.

Fastest way: use the app. Turn off ingredient reports, or withdraw shared photos in Settings → Label photos. Deleting the app deletes the data on your device.

By email: write to support@alphagalwise.com with the subject “Health Data Request.” Tell us your state, what you want, and anything that helps us find your data (for example, the date and product of a shared photo).

• We respond within 45 days. If we need more time, we may extend once by 45 more days and will tell you why.
• We don't charge for requests, and we won't treat you differently for making one.
• Because we don't keep names or device IDs with reports and photos, we may not be able to find data linked to you. If we can't, we'll tell you why. Anonymous reports can't be linked to anyone.
• An authorized agent may make a request for you, as your state's law allows.

How to appeal a decision

If we decline your request, in whole or in part, you can appeal. Reply to our decision, or email support@alphagalwise.com with the subject “Health Data Appeal,” within a reasonable time after our decision. We will respond in writing within 45 days, explaining what we did and why. If we deny your appeal, you can contact your state Attorney General:

• Washington: Washington State Office of the Attorney General
• Nevada: Nevada Attorney General
• Connecticut: Connecticut Attorney General

Changes to this policy

We may update this policy. Each version has its own revision label and effective date, shown at the top. If a change would let us collect, use, or share consumer health data in a new way, we'll ask for your consent first.
