Privacy policy

Who we are

Shelf to Shaker is provided by Margin Menu Lab. This policy covers the Android app, support enquiries and visits to this privacy-policy page. For privacy questions, contact info@marginmenulab.com.

Information used in the app

The app saves identifiers for the ingredients you select in local app storage on your device so that your shelf is available the next time you open the app. Search text is used temporarily while you use the app and is not saved as a search history.

The app does not require login, contain advertising or in-app purchases, or include developer-operated analytics or crash-reporting services. Shelf selections and searches are not transmitted to Margin Menu Lab or a third party by the app.

Local storage and your controls

Saved ingredient selections remain on your device until you change them, use the app’s “Clear all” control, or remove the app’s stored data through Android settings. “Clear all” replaces your saved shelf with an empty selection. If saving fails, the app displays an error.

This local storage is not encrypted by the app. Protect access to your device using its security controls. The app does not provide a cloud account or developer-operated backup service, and Android backup is disabled in the app configuration. We cannot retrieve or delete your on-device shelf remotely.

When you contact support

If you email us, we receive your email address and any information you choose to include. Our support mailbox is provided by Zoho Mail. We use your message to respond to your enquiry. Please do not send passwords or unnecessary sensitive information.

Support correspondence remains in our mailbox unless deleted. You can contact us to request access, correction or deletion of your support correspondence, or to raise a privacy concern. Please identify the enquiry so we can locate it.

Visiting this page and external services

Opening this policy online uses your browser and an internet connection. This website is hosted through OpenAI Sites using Cloudflare infrastructure. Hosting providers may process technical request information, such as your IP address and browser or device information, to deliver and protect the website. This is separate from the app’s local ingredient shelf and searches.

We have not added advertising trackers, analytics tools or contact forms to this policy page. Hosting-provider processing is described in the OpenAI Privacy Policy and Cloudflare Privacy Policy. If you email support, your email provider and our mailbox provider also process the email; see the Zoho Privacy Policy.

Adults only

Shelf to Shaker is intended for adults aged 18 and over. Follow the legal drinking age and alcohol laws that apply where you live.

Changes to this policy

We may update this policy if the app or our data practices change. The effective date above identifies this version. Contact info@marginmenulab.com with questions.
