Veganalysis is a barcode-scanning app that identifies likely non-vegan ingredients in packaged products. It runs on your device, holds no account, and Skyline Trail Computing collects nothing about you, your scans, your usage, or your device. There is no analytics SDK, no telemetry, no advertising, no in-app purchases.
When the app needs to look up a product it does not already have on your device, it sends the product’s barcode to Open Food Facts, a non-profit open-data project. Open Food Facts therefore sees that someone (your IP address, the request timing) asked about that barcode. Open Food Facts is a separate organization with its own privacy practices: https://world.openfoodfacts.org/.
That outbound Open Food Facts call is the only data plane Veganalysis initiates on its own. There is one additional path, user-initiated only, described next.
Veganalysis includes two in-app features that let you compose and send a message to Skyline Trail Computing through your own email client: “Send Feedback” (which packages scans you have flagged in-app into a feedback bundle) and “Report a Problem” (a free-text draft for general app problems, with no attached scan data). In both cases, the contents you compose are received by us via your email client. This is voluntary and user-initiated; no other data is collected.
The “Send Feedback” bundle contains only the scans you have flagged in-app (either to report a verdict you disagree with, or to attach a barcode for a product you scanned via the OCR fallback). Camera frames, location, device identifiers, account information, and product images are never included. You see the email — including the JSON attachment — in your own mail composer before sending; you can edit, attach, or discard at will. Nothing is sent automatically, in the background, or without your explicit Send action in your mail client.
The “Report a Problem” draft contains the text you write plus a
small auto-filled context block — your app version, iOS version,
device model class (e.g., iPhone16,2), and locale. None of
these uniquely identify you or your device. The draft has no
attachment. As with “Send Feedback”, you see and can edit the
entire message in your own mail composer before sending, and
nothing is sent without your explicit Send action.
If your device does not have a configured mail account, the app offers a system Share Sheet for “Send Feedback” so you can route the bundle through another messaging app of your choice. For “Report a Problem”, the app surfaces our contact email address as selectable text so you can copy it into the messaging app of your choice. That choice remains entirely yours in either case.
iOS removes all of this when you uninstall the app.
Only this: an HTTPS GET request to the Open Food Facts API at
world.openfoodfacts.org/api/v2/product/<barcode>.json, sent only
when the scanned product is not already in the bundled database or
the on-device cache.
The request includes:
Veganalysis-iOS/0.1).It does not include: your name, account, email, device identifier, location, advertising identifier, contacts, photos, or any other personal information. Veganalysis does not collect or hold any of those things in the first place.
Because Open Food Facts receives the request directly:
Open Food Facts is run by the Open Food Facts Association (a French non-profit). Their handling of any information they receive is governed by their own privacy policy, linked above.
Veganalysis uses your device’s camera to read product barcodes. Camera frames are processed in memory on your device and discarded immediately after the barcode is decoded. Camera frames are never stored on your device, transmitted off your device, or shared with anyone, including Skyline Trail Computing.
iOS will ask your permission before Veganalysis accesses the camera. You can revoke access at any time in iOS Settings → Privacy & Security → Camera.
There are none. Veganalysis ships with no analytics SDK, no advertising SDK, no crash-reporting SDK, no third-party data plane of any kind. The Apple-mediated crash and usage diagnostics that you may have opted into in iOS Settings → Privacy & Security → Analytics & Improvements are sent to Apple under Apple’s own policies — Veganalysis does not see or receive that data.
None of these exist in Veganalysis, and there is no plan to add them. Veganalysis is free, with no in-app purchases, no subscriptions, and no advertising.
Veganalysis is not directed at children under 13. Because Veganalysis does not collect any personal information from any user, it does not knowingly collect personal information from children either. Skyline Trail Computing has no mechanism by which any user, of any age, could provide personal information through this app.
Various jurisdictions give you rights over personal information about you that a company holds. Skyline Trail Computing holds no personal information about you. There is therefore nothing for us to disclose, correct, port, or delete on request.
Open Food Facts, as a separate data processor, has its own obligations and processes regarding any data they receive — see their privacy policy.
If this policy materially changes, the change will be reflected in an
updated Last updated date at the top of this document, in a note in
the app’s release notes, and in the commit history of this repository.
This policy covers privacy practices only. Veganalysis identifies likely non-vegan ingredients from product labels. It is not a guarantee, and it is not designed for allergen safety. People with allergies must contact the manufacturer for definitive ingredient and cross-contact information. The in-app disclaimers and the App Store listing carry the app’s accuracy and allergen disclaimers in full.
