• customer support;
• feedback forms;
• analytics and diagnostics;
• app-related communications;

Some products may include additional product-specific notices. If a product-specific notice conflicts with this Privacy Policy, the product-specific notice applies for that product.

3. Information We Collect

Depending on the product or feature you use, we may collect or process the following information.

3.1 Information You Provide

We may collect information you voluntarily provide, such as:

• name;
• email address;
• support messages;
• feedback;
• bug reports;
• feature requests;
• billing, refund, privacy, or legal request details;
• information you include when contacting us.

Please do not send sensitive personal information unless it is necessary for your request.

3.2 App and Device Information

Our apps may process technical and usage information, such as:

• app version;
• device type and model;
• operating system version;
• language and region;
• app settings;
• premium or subscription status;
• app screens, navigation, and feature usage;
• search usage metadata, such as query length or search interaction type;
• conversion workflow events, such as whether a conversion started, succeeded, failed, or was abandoned;
• favorites, history, paywall, purchase, and restore interactions;
• error codes, status values, duration buckets, and similar diagnostic metadata;
• app instance identifiers, installation identifiers, customer identifiers, or similar technical identifiers.

We do not intentionally send raw conversion input values, raw conversion result values, raw unit-search text, or personally typed conversion content to analytics providers.

3.3 Crash and Diagnostic Information

We may collect crash and diagnostic information, such as:

• crash logs;
• stack traces;
• non-fatal errors;
• device model;
• operating system version;
• app version and build number;
• runtime state needed to debug crashes;
• non-sensitive app context, such as selected screen, selected category, selected unit identifiers, language, premium status, or precision settings.

We do not intentionally include raw conversion input values, raw conversion result values, raw unit-search text, or personally typed content in crash reports.

3.4 Purchase and Subscription Information

If you purchase, subscribe, start a trial, cancel, or restore purchases, we and our service providers may process:

• purchase history;
• subscription status;
• trial or offer eligibility;
• product identifiers;
• transaction identifiers;
• receipt or purchase-token information;
• app user, customer, installation, or device identifiers;
• entitlement or premium status;
• purchase, restore, cancellation, or subscription error/status information;
• billing country, currency, locale, or storefront where provided by the app store or service provider.

Payment processing is handled by the applicable app store, platform, or payment provider. We do not directly receive or store your full payment card number.

You can manage or cancel subscriptions through your app store account settings.

3.5 Website Information

When you visit our website, we may process:

• IP address;
• browser type;
• device type;
• operating system;
• pages viewed;
• referring pages;
• approximate region;
• date and time of visit;

Our website may use cookies, local storage, or similar technologies for functionality, security, analytics, performance, preferences, and abuse prevention.

3.6 Local App Data

Some information may be stored locally on your device, such as:

• app language;
• theme;
• decimal precision;
• onboarding status;
• premium status cache;
• paywall state;
• favorite conversions;
• recent conversion history;
• last selected units;
• local settings and cached data.

Local favorites or history may include selected units, entered values, conversion text, or conversion results. This information generally remains on your device unless a feature requires communication with us, an app store, or a service provider.

Deleting an app may remove local app data from your device, but it does not cancel an active subscription.

3.7 Currency, Reference Data, and API Requests

Some products may use external providers for currency rates, reference data, scientific data, AI-assisted features, or similar services.

Depending on the feature, these providers may process technical request information such as:

• IP address;
• request time;
• requested currency pair, unit, date, or reference-data item;
• browser or device metadata;
• error and performance information.

Where possible, we avoid sending personal content to external data providers unless the feature requires it.

• provide customer support;
• respond to privacy, billing, refund, or legal requests;
• measure app usage and improve product design;

5. Legal Bases for Processing

Where a legal basis is required, including under the GDPR, UK GDPR, or similar laws, we process personal information based on one or more of the following legal bases.

Contract

We process information when needed to provide apps, subscriptions, purchases, support, and requested services.

Legitimate Interests

We process information for legitimate interests such as operating, securing, debugging, improving, and supporting our products; preventing fraud; understanding product performance; and maintaining business records.

Consent

We rely on consent where required for optional analytics, cookies, tracking, marketing, or similar technologies.

Where we rely on consent, you may withdraw consent at any time using available app, website, browser, device, platform, or support options.

Legal Obligation

We process information where necessary to comply with laws, tax rules, accounting rules, app store rules, legal requests, and regulatory obligations.

6. Third-Party Service Providers

We use third-party service providers to operate, improve, secure, support, and monetize our website, apps, subscriptions, and related services.

7. App Stores and Payments

If you download, purchase, subscribe to, or restore a Strujic Labs app through an app store or platform, that provider may process information independently under its own terms and privacy policy.

App stores and platform providers may handle:

• payment processing;
• billing;
• subscription renewals;
• subscription cancellation;
• refunds;
• tax;
• fraud prevention;
• purchase records;
• account management;
• app store compliance.

We do not control the privacy practices of app stores or payment providers.

8. Cookies and Similar Technologies

Where required by law, we request consent before using non-essential cookies, analytics technologies, or similar technologies that store or access information on your device.

Strictly necessary technologies may be used without consent where required for:

• website operation;
• app functionality;
• security;
• subscription verification;
• fraud prevention;
• requested services.

You can control cookies through browser settings and manage device permissions, diagnostics sharing, tracking permissions, and similar choices through your device or platform settings.

9. Disclosure of Information

We may disclose information:

• to service providers that help operate our website, apps, subscriptions, analytics, diagnostics, support, security, payment, and infrastructure;
• to app stores, payment processors, or platform providers for purchases, subscriptions, refunds, entitlement verification, and store compliance;
• to external data or API providers where a feature requires their service;
• to comply with law, legal process, or government requests;
• to protect rights, property, safety, security, users, systems, or the public;
• to investigate fraud, abuse, unauthorized access, or security incidents;
• in connection with a merger, acquisition, financing, reorganization, sale of assets, or similar business transfer;
• with your consent or at your direction.

We do not sell or rent personal information.

We do not use personal information from our apps to build third-party advertising profiles.

If a product ever uses tracking, targeted advertising, cross-app advertising identifiers, or similar technologies where consent is required, we will provide the required notice and choices before doing so.

We do not knowingly sell or share personal information of children under 16.

10. International Processing

Our website and apps may be available worldwide. Information may be processed in your country, the European Economic Area, the United Kingdom, the United States, or other countries where we or our service providers operate.

These countries may have privacy laws that differ from those in your jurisdiction.

Where required, international transfers are handled using appropriate legal mechanisms and safeguards, such as:

• adequacy decisions;
• standard contractual clauses;
• data-processing agreements;
• recognized data-transfer frameworks;
• contractual protections;
• technical and organizational safeguards;
• other lawful transfer mechanisms.

11. Retention

We keep information only as long as reasonably necessary for the purposes described in this Privacy Policy, unless a longer period is required or permitted by law.

Examples:

• local app data remains on your device until you delete it, clear it, or delete the app;
• support messages may be kept as needed to respond to you and maintain business records;
• purchase and subscription records may be kept for entitlement management, support, fraud prevention, accounting, legal compliance, and app store compliance;
• analytics, crash, subscription, and diagnostic data may be kept according to our settings and our providers’ retention practices;
• legal, tax, accounting, security, and business records may be kept as required or permitted by law.

12. Your Choices and Rights

Depending on where you live, you may have privacy rights under laws such as the GDPR, UK GDPR, California privacy laws, other US state privacy laws, Brazil’s LGPD, Canada’s privacy laws, Australia’s Privacy Act, Japan’s APPI, South Korea’s PIPA, India’s DPDP Act, or similar laws.

These rights may include the right to:

• access your personal information;
• correct inaccurate personal information;
• delete personal information;
• restrict or object to certain processing;
• request data portability;
• withdraw consent where processing is based on consent;
• opt out of sale, sharing, targeted advertising, or profiling where applicable;
• limit use of sensitive personal information where applicable;
• appeal a privacy decision where applicable;
• file a complaint with a privacy authority.

To exercise privacy rights, contact:

info@strujiclabs.com

We may need to verify your request before responding.

Some information may be retained where required or permitted by law, including for security, fraud prevention, tax, accounting, legal compliance, dispute resolution, subscription records, or app store compliance.

If GDPR or UK GDPR applies, we will respond to valid privacy requests without undue delay and generally within one month. If a request is complex or we receive many requests, we may extend the response period where permitted by law and notify you.

Because some Strujic Labs apps do not maintain user accounts or server-side profiles, we may have little or no information that can be identified as yours unless you provide enough information for us to locate it.

13. Children

Our website and apps are intended for a general audience and are not directed to children under 13 or to children under the minimum age required by local law.

We do not knowingly collect personal information from children where parental consent is required.

If we learn that we have collected personal information from a child where parental consent was required, we will take appropriate steps to delete it.

14. Informational Content

Some Strujic Labs products may include converter tools, calculator tools, scientific units, medical laboratory units, currency rates, reference data, explanatory text, AI-assisted outputs, or other informational features.

These features are provided for general informational purposes only.

They are not medical devices, financial advisers, laboratory systems, legal advisers, safety-critical engineering tools, navigation systems, emergency systems, certified calibration tools, or professional compliance systems.

You should avoid entering information that identifies a patient or another person unless a product feature clearly requires it and explains how that information is processed.

15. Security

We use reasonable technical, organizational, and administrative measures designed to protect information from unauthorized access, loss, misuse, alteration, or disclosure.

No method of transmission or storage is completely secure, and we cannot guarantee absolute security.

16. Changes to This Policy

We may update this Privacy Policy when our website, apps, legal requirements, service providers, subscriptions, data practices, or product features change.

Updates will be posted on this page with an updated effective or last-updated date.

Material updates may also be provided in the relevant app, support page, app store listing, or another appropriate method.
