Privacy Policy

Your profile stays on your phone. You choose what to send for a meal estimate.

Last updated: October 19, 2026

Stavna is operated by Trembita Digital LLC (“we”, “us”, or “our”). This policy explains how the app and stavna.app handle information. For privacy questions, contact [email protected].

No registration

Stavna does not require an account, email address, or password. Set up your profile once and start tracking.

Your profile and diary

Your age, sex, height, weight, weight history, activity, goals, preferences, meal diary, and saved photos are stored locally in the app. Stavna does not send your profile or weight history to its server or to the AI provider. Your daily calorie goal is calculated on your device and can be adjusted manually.

Stavna does not provide a cloud account or diary sync. Your operating system may include app data in device backups, depending on your Apple or Google backup settings. We do not receive or manage those backups.

Optional voice input

You can dictate a meal description using your phone’s speech-recognition service. Microphone and, on iOS, speech-recognition permission are requested when you choose dictation. Depending on the device, language, settings, and speech provider, recognition may happen on the phone or involve sending audio to that provider’s servers under its terms. Offline recognition is not guaranteed.

Stavna does not create or store audio recordings or upload audio to its server or AI service. Recognized text appears in an editable field. Only when you request a meal estimate is the description sent through Stavna’s AI flow described below. You can use typed input instead and manage microphone and speech permissions in your phone’s settings.

AI meal analysis

Stavna AI estimates calories and nutritional values from the meal content you choose. When you request an estimate, the selected meal photo or meal description you typed or dictated is sent over HTTPS through Stavna’s server to an external AI service. Corrections may also include your text, the earlier meal description, and the earlier calorie estimate. Your selected reply language is used to format the result.

Our server processes meal content only to complete your request. Uploaded files may be handled temporarily during processing; we do not keep meal photos, descriptions, corrections, or AI results in a permanent server database or server-side diary.

External AI services may retain submitted content and responses for up to 30 days under their standard commercial API policies. Longer retention may apply for safety reviews, usage-policy enforcement, or legal obligations. API submissions are not used for model training by default; exceptions may include explicit opt-in or feedback shared with a provider. For questions about the services used, retention, or deletion, contact [email protected].

AI analysis is optional. Only send the meal content you want analysed; do not include personal details in photos or descriptions. You can stop submitting requests at any time. Providers may process submitted information outside your country.

Local retention and deletion

Meal records, your profile, and weight history remain in the app until removed. You can delete individual meals or use Settings → Delete history to remove the meal diary and its saved photos. This control does not erase your profile or weight history.

Settings → Keep photos lets you choose 7, 30, or 90 days; the default is 30 days. Older saved photos are removed when the app loads or you change this setting. The meal records remain. Photos already in your phone’s photo library are not deleted by Stavna.

To remove all local Stavna data, clear the app’s storage on Android or delete the app on iOS rather than offloading it. Device backups are managed through your operating system. Removing local records does not delete an earlier submission from an external AI service. Those submissions remain subject to the service’s retention and deletion policies.

Apple Health

On iPhone, Stavna can write the weight you enter to Apple Health if you enable it in Settings and grant permission. It requests write access to weight only. Stavna does not read Health data or send it to its server, advertisers, or the AI provider.

You can turn this feature off in Stavna or revoke permission in your device’s Health settings. This stops future writes. Weight records already saved to Apple Health remain there until you remove them in the Health app.

Purchases and app security

Purchases and subscriptions, when available, are processed by Google Play or Apple’s App Store. We do not receive your full payment card details. App and purchase verification may send proof tokens, purchase receipts, or verification identifiers to our server and the relevant platform. They are used to confirm access and prevent abuse, separately from your profile and diary.

Our server retains used security challenge identifiers until they expire and a later session request removes them. For iOS App Attest verification, it can retain an installation’s key identifier, public key, and registration time. These records do not contain your personal profile or meal diary.

Website, logs, and security

Our hosting and network services, including Cloudflare, handle technical information needed to deliver and protect the website and API. This can include IP addresses, request times, requested paths, browser or app information, and response status. Our API’s operational logs record request metadata, rather than meal photos or request bodies. See Cloudflare’s privacy policy for its processing.

Operational logs and registered app-verification keys currently have no automatic age-based deletion. They remain until removed for maintenance or in response to an identifiable, verified privacy request, subject to security and legal retention needs.

The website uses Google Analytics to measure visits and page views and may set analytics cookies in your browser. The administration area also uses a sign-in cookie.

We use HTTPS for the app’s production API connection and connections to external AI services. No method of transmission or storage is completely secure. The mobile app does not include advertising, analytics, or crash-reporting SDKs, and we do not sell personal information.

Your choices and privacy requests

You control AI submissions, local deletion, camera, photo, microphone and speech permissions, and Apple Health access. We use submitted meal content to provide the estimate you request and technical records to operate and protect the service.

Depending on applicable law, you may have rights to access, correct, delete, or receive a copy of personal information, restrict or object to its processing, withdraw consent, or complain to a data protection authority. Email [email protected] to make a request. We may need enough information to locate a record and verify your request. We cannot retrieve your locally stored profile or diary from our server.

If you contact us, we receive your email address and the information in your message. We use it to answer your inquiry or handle your request, and retain correspondence as needed to resolve it and meet applicable obligations. Avoid sending unnecessary health information.

Adults and calorie estimates

Stavna is intended for adults aged 18 and older, and profile setup accepts ages 18–100. It is not designed for children. Contact us if you believe a child has submitted personal information through our service.

Calorie and nutritional estimates can be inaccurate. Stavna is not a medical device and does not provide medical advice, diagnosis, or treatment. Read our disclaimer.

Changes and contact

We may update this policy as the service or applicable requirements change. The current version will be published here with a revised date.
