Privacy Policy for websites, software services, and published mobile applications

Policy overview

This document is intentionally detailed because our services may involve public websites, internal business systems, mobile management applications, app marketplace distribution, analytics tooling, advertising monetization, and multiple regional legal environments. The policy is designed to help individual users, business customers, internal reviewers, and platform operators understand the same data practices from a common source.

How to read this policy

If you are a website visitor, the most relevant sections are the sections on information collection, use, cookies, regional rights, and contact. If you are an app user, you should also read the sections covering app stores, advertising and monetization, analytics, age restrictions, and international data transfers. If you are a business customer or administrator, you should additionally review the sections on legal bases, sharing, data retention, cross-border processing, and user rights handling.

1. Scope and products covered

This Privacy Policy covers:

1. the public-facing corporate website and all related landing pages;

3. How we use personal information

We may use personal information for the following purposes:

1. to provide, operate, maintain, secure, and improve our websites, apps, software products, consulting services, and support services;
2. to authenticate users, administer accounts, enforce access permissions, and support mobile management functions;
3. to respond to support requests, business inquiries, enterprise account requests, partnership opportunities, and operational issues;
4. to publish, operate, update, and manage applications distributed through Google Play, Apple App Store, and other stores;

9. to comply with legal obligations, respond to lawful requests, maintain records, exercise legal rights, and defend claims; and
10. to support commercial operations related to daily necessities, household goods, electronic products, office supplies, and hardware products when digital services or business systems are involved.

4. Legal bases for processing

Where required by law, we rely on one or more of the following legal bases:

• performance of a contract or steps taken at your request before entering a contract;
• our legitimate interests in operating, securing, improving, marketing, and administering our services, provided those interests are not overridden by your rights and freedoms;
• your consent, including consent for certain cookies, certain analytics, certain forms of personalized advertising, push notifications, or access to device permissions where required;
• compliance with legal obligations; and
• protection of vital interests, public interest tasks, or other lawful grounds recognized under applicable law.

5. App stores, app publishing, and platform-specific compliance

Our applications may be distributed through Google Play, Apple App Store, and other app marketplaces. When we publish or manage such applications, we seek to align our privacy disclosures and operational practices with store requirements, including transparency about data collection, data sharing, account deletion where applicable, subscription or purchase disclosures where applicable, age suitability, and use of advertising and analytics SDKs.

Google Play users may also be subject to Google policies, Google Play Terms of Service, Google Play data safety disclosures, and Google advertising identifiers rules. Apple App Store users may also be subject to Apple media services terms, App Tracking Transparency requirements where applicable, Apple privacy nutrition label frameworks, and Apple platform rules. Other app stores may impose their own disclosure, review, payment, or age-rating requirements. Your use of those stores is also governed by the separate terms and privacy policies of the relevant platform operator.

Where required, our applications may request runtime permissions, display store-compliant notices, offer privacy choices, or provide access to deletion and support channels. Store-specific disclosures supplement this policy and may appear in app listings, onboarding screens, consent prompts, or in-app privacy settings.

6. Advertising, monetization, and third-party advertising platforms

Some of our applications may display or facilitate advertising to support service availability, app monetization, or commercial objectives. Typical ad formats may include open app ads, splash ads, app launch ads, rewarded video ads, rewarded interstitial ads, interstitial ads, banner ads, adaptive banner ads, native ads, and related measurement or mediation units. Depending on the app, we may integrate, test, or use one or more advertising or monetization partners, directly or through mediation or bidding technology.

Advertising, monetization, mediation, measurement, demand, and ad-tech partners that may be used now or in the future include, without limitation, Google AdMob, Google Ad Manager, Google AdSense for applicable web surfaces, AppLovin, AppLovin MAX, Unity Ads, ironSource, LevelPlay, Liftoff, Vungle, Meta Audience Network, Mintegral, Pangle, TikTok for Business integrations where applicable, Chartboost, InMobi, Start.io, Smaato, Digital Turbine, Fyber, BidMachine, Yandex Ads, Amazon Publisher Services, PubMatic, Moloco, AdColony where legacy support exists, and other lawful regional demand or mediation providers that may be integrated for monetization, waterfall optimization, bidding, analytics, anti-fraud, or ad-quality purposes.

These platforms may collect or receive data such as advertising identifiers, device identifiers, IP address, approximate location, app interactions, impression data, click data, conversion data, crash diagnostics, fraud-prevention signals, and consent signals. Some platforms may use cookies, SDKs, pixels, server-to-server integrations, or similar technologies to provide ad delivery, measurement, attribution, audience controls, frequency capping, and policy enforcement.

Where required by law, we seek to obtain consent before enabling personalized advertising or certain tracking technologies. We may also support limited ads, contextual ads, non-personalized ads, or age-restricted treatment where necessary. For apps directed to mixed audiences or where minors may be present, additional controls may be applied, including disabling personalized advertising, limiting data sharing, or adjusting age treatment flags.

Advertising partners operate under their own privacy terms and may act as independent controllers, separate businesses, service providers, processors, or joint participants depending on the data flow and applicable law. We encourage users to review the privacy information provided by those third parties. We do not control all downstream practices of third-party ad networks once data is transmitted in compliance with your settings or the product configuration.

7. Analytics, diagnostics, and product improvement

We may use analytics, diagnostics, and reporting tools to understand performance, app stability, feature usage, and operational effectiveness. These tools may include first-party logging, store analytics, crash reporting, performance monitoring, campaign analytics, and third-party measurement products. Analytics data helps us improve service quality, understand adoption patterns, manage risk, and allocate support resources. Where required, analytics functions may be subject to consent, regional restrictions, or additional in-app disclosure.

8. Cookies, SDKs, local storage, and similar technologies

Our website and apps may use cookies, local storage, pixels, tags, software development kits, and similar technologies to remember preferences, keep you signed in, measure usage, prevent fraud, store consent choices, deliver content, support advertising, and improve performance. You may be able to control some of these technologies through browser settings, device settings, platform permissions, or in-app preference tools. Blocking certain technologies may reduce functionality or availability of some services.

9. How we share personal information

We may share personal information as reasonably necessary with:

• service providers, vendors, cloud providers, analytics providers, communication tools, customer support tools, security partners, and professional advisors;
• app stores, payment processors, distribution partners, and device ecosystem providers;
• advertising, attribution, fraud-prevention, mediation, and monetization partners as described above;
• enterprise customers, account administrators, or organizational managers when an app or service is used as part of a managed business environment;
• business partners, acquirers, successors, or affiliates in connection with a merger, acquisition, financing, reorganization, sale of assets, or similar transaction; and
• law enforcement, regulators, courts, or other parties when required by law or reasonably necessary to protect rights, safety, property, or the integrity of our business and users.

10. International data transfers

Because we serve international users and may use vendors, cloud services, content delivery systems, analytics providers, and advertising partners operating across multiple jurisdictions, personal information may be transferred to and processed in countries other than the country in which you reside. Where required, we implement appropriate safeguards for cross-border transfers, which may include contractual commitments, recognized transfer mechanisms, risk assessments, access controls, encryption, and data minimization measures. However, international transfers may still carry risks, and legal protections may differ from those in your home country.

11. Regional privacy disclosures

11.1 European Economic Area, United Kingdom, and Switzerland

For users in the European Economic Area, United Kingdom, and Switzerland, you may have rights to access, rectify, erase, restrict, object to certain processing, and request data portability, subject to exceptions. You may also withdraw consent where processing relies on consent. If you believe our processing violates applicable data protection law, you may complain to a relevant supervisory authority. We recognize obligations arising under the General Data Protection Regulation, the UK GDPR, the Data Protection Act 2018, and comparable Swiss privacy principles where applicable.

11.2 United States

For residents of California and other applicable U.S. states, including Virginia, Colorado, Connecticut, Utah, and other states with consumer privacy laws in effect now or in the future, you may have rights to know, access, correct, delete, and opt out of certain processing activities such as targeted advertising, profiling, or certain data sharing, subject to applicable exceptions. We do not knowingly sell personal information in exchange for monetary consideration in the narrow sense unless a disclosure and lawful basis exists; however, some ad-tech activities may be considered sharing, targeted advertising, or cross-context behavioral advertising under certain laws. You may contact us to exercise applicable rights.

11.3 Brazil

For users in Brazil, we aim to align our processing with the Lei Geral de Protecao de Dados, including lawful basis requirements, transparency, security, and rights to confirmation, access, correction, anonymization, portability, deletion, and review of certain automated decisions where applicable.

11.4 Canada

For users in Canada, we seek to support fair information principles consistent with PIPEDA and applicable provincial privacy laws, including meaningful consent where required, reasonable purposes, and access rights.

11.5 Australia and New Zealand

For users in Australia and New Zealand, we aim to respect applicable privacy principles including notice, fair handling, security, access, correction, and complaint pathways where relevant under the Privacy Act 1988, the Australian Privacy Principles, the Privacy Act 2020, and related frameworks.

11.6 Asia-Pacific and other jurisdictions

Where our services reach users in Singapore, Hong Kong, Japan, South Korea, India, the United Arab Emirates, Saudi Arabia, or other jurisdictions with privacy laws, we seek to adapt our practices as required by applicable rules such as PDPA, PDPO, APPI, PIPA, DPDP, PDPL, or equivalent local frameworks. Rights, consent standards, retention expectations, localization requirements, and cross-border transfer conditions may vary by country and app context.

12. Age restrictions and children's privacy

Our corporate website is intended for general business audiences. Some apps may be intended for adults, business users, or users above a specified minimum age. Unless a specific app explicitly states otherwise, our services are not knowingly directed to children under 13, and in some jurisdictions stricter thresholds may apply, such as under 16 or under the locally defined digital age of consent. Where a product is intended for older teens or mixed audiences, we may apply additional safeguards including age-gating, limited data collection, restricted profiling, or non-personalized advertising treatment.

If we learn that we collected personal information from a child in violation of applicable law, we will take steps to delete or de-identify that information and to disable inappropriate processing. Parents, guardians, or legal representatives who believe a child has submitted information to us may contact support@dachaotech.com.

13. Data retention

We retain personal information for as long as reasonably necessary for the purposes described in this policy, including to provide services, maintain business and tax records, comply with legal obligations, resolve disputes, enforce agreements, protect rights, support audits, and preserve security logs. Retention periods vary based on the type of data, the service context, the sensitivity of the information, whether an account remains active, contractual requirements, and applicable legal rules. We may retain aggregated or de-identified information for longer periods where permitted.

14. Security measures

We use administrative, technical, and organizational measures designed to protect personal information, including role-based access controls, vendor management, encryption where appropriate, logging, secure development practices, authentication mechanisms, and internal review processes. No method of transmission or storage is completely secure, and we cannot guarantee absolute security. Users should also protect credentials, device access, and communication channels.

15. Your choices and rights

Depending on your location and the service you use, you may have the right to:

• access and obtain a copy of certain personal information;
• correct or update inaccurate information;
• delete certain information or request account deletion where applicable;
• object to or restrict certain processing;
• withdraw consent where processing is based on consent;
• opt out of certain personalized advertising or targeted advertising activities;
• manage cookies, identifiers, app permissions, and communication preferences; and
• appeal a denied privacy request where required by law.

To exercise rights, contact support@dachaotech.com and provide enough detail for us to evaluate your request. We may need to verify your identity, the authority of an agent, or the scope of the request before acting.

16. Do Not Track and global privacy preference signals

Some browsers and extensions offer Do Not Track signals or global privacy controls. Because standards remain inconsistent across technologies and jurisdictions, our response may vary depending on the environment, applicable law, technical feasibility, and the specific service. Where legally required, we will seek to honor valid signals or provide other methods to exercise relevant choices.

17. Business transfers and organizational changes

If all or part of our business, product lines, assets, or applications are involved in a merger, acquisition, financing, restructuring, or sale, personal information may be transferred as part of that transaction subject to applicable confidentiality, notice, and legal requirements.

18. Updates to this policy

We may update this Privacy Policy from time to time to reflect legal changes, product changes, new integrations, new advertising partners, app store rule changes, or operational needs. The updated version will be posted on this page with a revised effective date. Where required by law or platform rules, we may also provide additional notice inside a website or app, or request consent again.
