Overview

Embrella Labs Ltd ("Embrella", "we", "us") is responsible for the personal information we process as described in this policy. We collect only what is necessary to provide the service and never sell your personal data. You can contact us at support@embrella.app.

Embrella Labs apps include ZenSpark Alarm, Aindly App, Fiberbelly, Stamna, and other applications published under the Embrella Labs developer account on the Apple App Store and Google Play.

Data practices and third-party services vary by app. The advertising, purchase and analytics services mentioned below are not present in every app; the Stamna section explains which practices apply to Stamna.

Information We Collect

Depending on the app, we may collect:

• In-app purchase history — to verify your subscription or purchase status, where purchases or subscriptions are offered (processed via RevenueCat).
• Crash logs, diagnostics, and app statistics — to identify bugs, understand reliability, and improve performance, where the app uses these services. Depending on the service, this may include a pseudonymous app or device identifier. Stamna does not include an analytics or crash-reporting service.
• Local app data — such as alarms, preferences, scanned product details, ingredient results, fiber entries, daily goals, mascot customisation choices, streak progress, and Stamna's fitness profile and workout records. These records are saved in the app's local storage and are not uploaded to Embrella Labs servers. Device backups are separate, as explained below.

Personal details you choose to enter in Stamna remain in its local profile. If you contact us directly, we receive the information you send, including your email address and message. Device and app identifiers handled by third-party services are described in the relevant sections below.

How We Use Your Information

• To deliver and improve app functionality
• To process and validate in-app purchases
• To diagnose crashes and fix bugs
• To serve ads (where applicable)
• Within Stamna, to prepare and adapt workout plans, save preferences, display progress and schedule reminders on your device

Notifications

With your permission, our apps may send local notifications (for example, to trigger alarms). We do not send marketing or remote push notifications.

Stamna requests notification permission when you enable workout reminders. Its reminders are scheduled on your device. You can switch them off in Settings → Reminders or your device's notification settings. Notification text may reveal a planned workout on your lock screen; your device settings control whether previews are shown.

Advertising

Some of our apps may display ads via Google AdMob. AdMob may collect device identifiers and usage data to serve relevant ads. On iOS, you will be prompted for permission before any advertising identifier is accessed. See Google's Privacy Policy for details.

Stamna does not display ads, access advertising identifiers or track activity across other companies' apps and websites.

Third-Party Services

Our apps may use the following third-party services, each with their own privacy policy:

• RevenueCat — subscription and purchase management in apps that use it. Receives purchase records and app user identifiers to validate access; these records are not necessarily anonymous.
• Google AdMob — advertising. May collect device identifiers and usage data.
• Firebase Analytics — in apps that integrate it, used to understand how the app is used and improve its features. Firebase Analytics may collect a pseudonymous app-instance/device identifier, app interactions such as launches, screens and sessions, device and app metadata, and approximate geographic information derived from a masked IP address. We do not use this information for cross-app tracking or advertising.
• Apple / Google — app distribution, payment processing, and crash reporting.

Data Security

Data transmitted to the third-party services described above uses HTTPS. Stamna saves its profile and workout records in local app storage and does not upload them to our servers. Local records rely on your device's or browser's storage protections; Stamna does not provide a separate password or encryption feature for these records. Protect access to your device and any backups.

Data Retention and Deletion

For apps without an account system, including Stamna, there is no Embrella account to close, but local profiles and activity records may still exist. Local records remain until removed through the app's available controls or by clearing its storage. Deleting an installed app normally removes its local data; offloading an app may keep it. Device or cloud backups, previously exported files and records held by app stores or other services must be managed separately and may survive uninstallation.

App Privacy Details (Apple App Store & Google Play)

Data practices vary by app. The following covers our current apps:

ZenSpark Alarm

• Purchase history — collected by RevenueCat to validate subscriptions. Linked to your identity.
• Crash data — collected anonymously for diagnostics. Not linked to your identity.

ZenSpark does not use advertising SDKs and does not collect device identifiers, location, contacts, health data, or browsing history.

Aindly

• Purchase history — collected by RevenueCat to validate subscriptions or purchases, if offered. Linked to your identity.
• Crash data and app statistics — collected anonymously for diagnostics, reliability, and performance improvement. Not linked to your identity.

Aindly is an ingredients and product scanner for food and cosmetics. Scanned products, ingredient details, skincare preferences, analysis results, and scan history are stored on your device only and are not uploaded to Embrella Labs servers. Aindly does not collect your name, email address, location, contacts, photos, health data, or browsing history.

Fiberbelly

• Dietary and app data — information you choose to record, such as fiber intake, food entries, daily goals, mascot customisation, streak progress, and preferences, is stored on your device only and is not linked to your identity.
• Purchase history — collected by RevenueCat to validate subscriptions or purchases, if offered. Linked to your identity.
• Crash data and app statistics — collected anonymously for diagnostics, reliability, and performance improvement. Not linked to your identity.

Fiberbelly does not collect your name, email address, precise location, contacts, photos, or browsing history. Firebase Analytics may derive an approximate location from a masked IP address for analytics purposes.

Stamna

Stamna provides workout plans, exercise guidance and progress tracking without requiring an account. Its current version does not send your profile, workout history or local usage records to Embrella Labs or an analytics service.

• Personal details you enter — may include a first name or nickname, age, gender, height, current and target weight, body-build and desired-shape choices, weight goals, previous workout frequency and a selected obstacle to exercising. These are stored on your device. You can skip setup and browse workouts without completing a personal profile.
• Workout preferences — include your focus and goals, experience level, available equipment, preferred duration, standing-only or other movement preferences, push-up level, and body areas to focus on or go easy on. Body measurements and movement preferences can be sensitive and may reveal information about your health.
• Plans, history and local activity records — include current and previous plans, dates, exercise and session details, duration and movement time, completion or partial-completion status, difficulty feedback, progress and reminder settings. The app also keeps local setup and session events. Older saved records may include a chosen setting such as Home or Office, saved workouts, and previous-journal sets, repetitions and weights. A setting such as Home or Office is a user-selected category, not GPS location.
• How the data is used — the app applies rules on your device to select workouts, adapt pace, manage your plan, resume sessions, show progress and schedule reminders. Workout selection uses your workout preferences, plan progress and feedback; personal-detail answers such as name, age, height and weight do not determine workout selection. This does not involve sending your profile to an AI service or having a trainer review it remotely.
• Permissions and device data — reminders use optional notification permission. Stamna does not access your camera, microphone, contacts, photo library or GPS location, and does not connect to Apple Health/HealthKit, Google Health Connect or wearable health data. Exercise pictures and voice cues are bundled content; Stamna does not photograph or record you exercising.
• Purchases, advertising and analytics — Stamna currently has no in-app purchases, subscriptions, advertising, RevenueCat, AdMob or Firebase Analytics integration. Local participation events stay on your device. Apple or Google may separately handle app distribution and diagnostic information according to your platform settings and their policies.

Your controls. In Settings → Your profile → Saved personal details, choose Remove all saved personal details, then Save changes, to remove the personal-detail fields listed above. This does not remove your workout preferences, areas to focus on or go easy on, plans, history, reminders or local activity events. Areas to go easy on have a separate Clear excluded areas control. You can delete individual sessions from Progress; this does not erase all related local activity events.

Clearing all local records. Older journal recovery and restore copies may also remain in app storage; removing personal details or individual workouts does not clear those copies. Stamna does not currently provide an in-app control to erase all data. Use your operating system's app-data controls or delete the app to remove its local storage. For a browser version, clear that site's stored data. We do not hold a server copy of these records and cannot retrieve or erase them remotely.

Backups and device transfers. Stamna does not provide cloud sync, and the current interface does not offer backup export or import. Your operating system may nevertheless include app data in device backups or transfers, depending on your settings. Those copies are handled by your device or backup provider under its policies. Manage them separately; restoring a backup may restore data previously deleted from the app. Any files exported from an earlier version remain wherever you saved or shared them until you remove them.

Other Embrella Labs apps (where applicable)

• Identifiers (Device ID) — may be collected by Google AdMob for advertising in apps that display ads. Not linked to your identity.
• Usage data — may be collected by Google AdMob in apps that display ads. Not linked to your identity.

Children's Privacy

Our apps are not directed at children under 13. We do not knowingly collect information from children.

Contacting Us and Your Privacy Rights

If you email support, we and our email service provider process your address, message and any attachments to respond and resolve the issue. Stamna's bug-report email template includes its app version and platform; you choose whether to send it. Where UK or EEA data-protection law applies, our basis is our legitimate interest in providing support; we also process information where needed to meet legal obligations. Avoid sending health information or a complete workout history when it is not needed. Support correspondence is kept for as long as reasonably necessary to resolve the request, handle related follow-up or disputes, and meet applicable legal requirements.

Depending on the law that applies, you may request access, correction, deletion, restriction or portability of personal data we hold, object to its use, or withdraw consent where processing relies on consent. Contact support@embrella.app. For Stamna's on-device records, use the controls described above because we cannot access them remotely. You may also complain to the UK Information Commissioner's Office or your local data-protection authority.

Changes to This Policy

We may update this policy from time to time and revise the "Last updated" date. If a change introduces data collection or uses requiring your consent, we will request that consent before the processing begins. A policy update or continued use of an app does not by itself provide that consent.
