Effective date: June 27, 2026
Controller / Service Provider: LinhBUIH
Business support: linhbuih62@gmail.com
Key accounts: linhbuih62@gmail.com
This Privacy Policy applies to the LinhBUIH website and to LinhBUIH mobile applications and related services made available through Google Play, Apple App Store, and related distribution channels. It covers property management tools, landscape management tools, electronic equipment management tools, cleaning service task management tools, construction-industry consulting tools, and online application industry consulting services.
1. Scope and Applicability
This Policy applies to personal data processing carried out by LinhBUIH when you:
- Visit our website and interact with pages, forms, and analytics tags.
- Download or use our mobile applications from Google Play, App Store, and authorized stores.
- Use in-app services, communication channels, support channels, and operational dashboards.
- Participate in consulting engagements or business onboarding processes.
If local law requires additional disclosures, rights, legal bases, or consent mechanisms, those local requirements apply in addition to this Policy.
2. Categories of Personal Data We Process
- Identity and account data: name, business role, company name, account ID, support account details, and communication preferences.
- Contact data: email address, phone number (if provided), office location, and support correspondence.
- Device and technical data: device model, operating system version, app version, language settings, network type, advertising identifiers (where permitted), push token, and crash diagnostics.
- Usage and event data: app interactions, feature usage, navigation paths, task completion records, service logs, and engagement metrics.
- Operational data: property task records, landscape maintenance records, equipment maintenance records, cleaning task records, and project workflow metadata uploaded by enterprise users.
- Transaction and contractual data: service subscription records, project statements, invoices, and support ticket histories.
- Marketing and consent data: newsletter choices, consent status, jurisdictional consent strings (where used), and suppression preferences.
3. Sensitive Data and Special Categories
Our services are designed for business operations and generally do not require users to submit sensitive personal data or special-category data. If sensitive data is incidentally provided, we process it only where legally permitted and with additional safeguards, including access controls, encryption in transit, and strict retention limits.
4. Data Collection Sources
- Directly from you when you register, communicate with us, or use service features.
- Automatically from your device, browser, app SDKs, and server logs.
- From enterprise clients and administrators who provision service accounts.
- From integrated partners such as analytics providers, ad mediation platforms, and cloud service providers.
5. Purposes and Legal Bases
We process personal data for one or more of the following legal bases, depending on jurisdiction:
- Contract performance: to provide requested services, maintain accounts, and deliver support.
- Legitimate interests: to improve security, quality, performance, and operational reliability.
- Consent: where required for cookies, tracking technologies, ad personalization, push marketing, or specific data uses.
- Legal obligations: to comply with tax, accounting, consumer protection, and platform policy requirements.
6. App Store and Marketplace Compliance
Our app publication and operation practices are designed to align with:
- Google Play Developer Program Policies, Data Safety requirements, and Families policies where applicable.
- Apple App Store Review Guidelines, privacy nutrition labels, tracking transparency requirements, and age rating expectations.
- Applicable local consumer rights and digital-services regulations in target markets.
Where app store policy and law differ, we implement the stricter standard whenever feasible to protect user rights and maintain compliance continuity.
7. Advertising, Monetization, and Ad Platform Disclosure
Some LinhBUIH applications may include advertising monetization. Ads may be delivered through one or more platforms, including but not limited to:
- Google AdMob and Google Ad Manager
- Meta Audience Network
- AppLovin MAX
- Unity Ads
- ironSource
- InMobi
- Mintegral
- Vungle / Liftoff
- Pangle
- Chartboost
- Moloco
- Amazon Publisher Services / TAM (where implemented)
- Additional approved demand or mediation partners introduced over time
Ad formats can include App Open (splash/open-screen style), Rewarded Video, Interstitial, and Banner placements. Depending on applicable law and region, ad delivery may involve device identifiers, approximate location signals, contextual signals, campaign metadata, and fraud-prevention telemetry.
Where required by law, consent tools are presented for ad personalization and ad measurement. Users can withdraw consent or modify preferences in app settings or through device-level controls where supported.
8. Analytics and Measurement
We use analytics to understand service quality, app stability, usage trends, and product performance. Analytics events may include session timestamps, feature interactions, error signals, and aggregated conversion metrics. We do not knowingly use analytics to identify users directly unless required for support, security, or legal reasons.
9. Cookies, SDKs, and Similar Technologies
Our website and apps may use cookies, local storage, SDKs, and similar technologies for authentication, fraud prevention, performance measurement, advertising, and personalization. Where legally required, we implement a consent or opt-out mechanism before non-essential technologies are activated.
10. International Data Transfers
Because we serve Europe and North America and may use cross-border cloud infrastructure, personal data may be transferred across jurisdictions. We implement contractual and operational safeguards, such as standard contractual clauses, data processing agreements, transfer-impact assessments, and access controls, where required.
11. Data Retention
We retain personal data for as long as needed to deliver services, comply with law, resolve disputes, and enforce agreements. Retention periods vary by data category, contract requirements, and regulatory obligations. When retention is no longer required, data is deleted, anonymized, or irreversibly aggregated.
12. Security Measures
- Encryption in transit and, where practical, at rest.
- Role-based access controls and least-privilege principles.
- Security logging, anomaly detection, and incident handling workflows.
- Vendor due diligence and contractual security obligations.
- Regular patching and environment hardening practices.
No method of transmission or storage is absolutely secure. We encourage users to maintain strong account hygiene and report suspected abuse promptly.
13. Children and Age-Specific Requirements
Our core services are intended for enterprise and professional use. We do not knowingly collect personal data from children in violation of applicable law. Where an app may be accessed by younger users, we apply age-appropriate configurations and compliance controls.
- For U.S. users, we consider COPPA obligations for children under 13.
- For EEA/UK users, we respect local age-of-consent rules for information-society services.
- For app-store contexts, we align with age ratings and child-directed content restrictions.
- If we learn that child data has been collected improperly, we will take steps to delete it and restrict further processing.
14. Jurisdiction-Specific Privacy Rights
14.1 EEA and Switzerland (GDPR)
Individuals may have rights to access, rectify, erase, restrict, object, data portability, and lodge complaints with supervisory authorities. Where processing relies on consent, consent may be withdrawn at any time.
14.2 United Kingdom (UK GDPR and Data Protection Act 2018)
UK users have similar rights to EEA users, with complaints directed to the UK Information Commissioner's Office where appropriate.
14.3 United States (State Privacy Laws)
Depending on your state of residence, rights may include access, correction, deletion, data portability, and rights regarding targeted advertising or profiling. This includes laws such as CCPA/CPRA (California), VCDPA (Virginia), CPA (Colorado), CTDPA (Connecticut), UCPA (Utah), and other enacted state frameworks.
Where we process data on behalf of enterprise clients, rights requests may need coordination with the relevant enterprise controller.
14.4 Canada (PIPEDA and Provincial Laws)
Canadian users may request access and correction of personal information and may challenge compliance with privacy principles through applicable oversight mechanisms.
14.5 Brazil (LGPD)
Brazilian users may request confirmation of processing, access, correction, anonymization, deletion, portability, and information regarding sharing.
14.6 Australia and New Zealand
We support rights and complaint channels under applicable Australian and New Zealand privacy frameworks, including access and correction rights where required.
14.7 Asia and Other Regions
Where local privacy laws apply, including Singapore PDPA, Japan APPI, South Korea PIPA, India's Digital Personal Data Protection framework, UAE PDPL, Saudi PDPL, and South Africa POPIA, we provide appropriate rights handling and lawful processing controls as required.
15. Do Not Sell / Share, Targeted Advertising, and Preference Controls
In jurisdictions that define "sale," "sharing," or "targeted advertising" broadly, ad-tech data sharing may fall within those definitions. Eligible users can request opt-out of such processing where required by law. We will honor applicable preference signals and requests as required.
16. Data Subject Request Process
To submit a privacy request, contact us at linhbuih62@gmail.com. We may verify identity before fulfilling a request to protect users from unauthorized access. Authorized agents may submit requests where legally permitted and properly documented.
17. Third-Party Services and External Links
Our services may include links, APIs, SDKs, and integrations operated by third parties. Their privacy practices are governed by their own policies. We recommend reviewing those policies before use.
18. Enterprise Customer Role and Processor/Controller Distinction
For many business workflows, LinhBUIH acts as a processor/service provider on behalf of enterprise customers. In those cases, enterprise customers act as controllers/businesses for relevant personal data and define processing instructions and legal bases.
19. Automated Decision-Making
We do not intentionally use fully automated decisions with legal or similarly significant effects on individuals without appropriate legal basis, transparency, and safeguards.
20. Data Breach and Incident Notification
We maintain incident response procedures to identify, contain, investigate, and remediate security incidents. Where required by law or contract, we notify relevant parties and authorities within required timelines.
21. Changes to This Policy
We may update this Policy to reflect legal, technical, or operational changes. Material updates will be communicated through our website and, where required, in-app notices or other legally appropriate channels.
