How We Protect the Information We Collect

WMaster Cleanup is committed to protecting the security of your personal information. We used security technologies and procedures to safeguard your personal information.These measures include:

Storage of Your Information: We store the information you provide on computer systems with limited access, located in controlled facilities in the United States.

Technology Safeguards: We use encryption systems to prevent unauthorized access.

No one can guarantee your personal data is always secure. You yourself also need to maintain the confidentiality of any passwords to protect against unauthorized access or use.

How We Share Your Information

WMaster Cleanup does not share or disclose your personal information to any third parties with two exceptions:

Third-Party Service Providers: We contract with other businesses to handle some tasks for us, such handling payments and doing data analysis. These businesses are only permitted to collect the personal information required to provide the service. They are not allowed to use the information for any other reason and must keep it confidential.

Government and Law Enforcement: We may access and/or disclose your personal data if we think it's necessary to comply with the law or legal process.

How Long We Store Your Personal Data

Unless a longer retention time is mandated or authorized by law (for example, tax, accounting, or other legal requirements), we will only retain your personal information for as long as is necessary for the reasons outlined in this Privacy Policy. This policy does not require us to retain your personal information for any longer than the duration of a user's account with us.

For example:
· License and Billing Information: We retain your email address and license history for as long as you have a license and for a reasonable period afterward as required by financial and tax laws.
· Marketing Information: We store information used for marketing (if you opt-in) until you unsubscribe. When you unsubscribe, we will add your contact to a suppression list to respect your request.
· Analytics Data: We generally anonymize or delete this data within 60 months, as it is no longer needed for analysis.

We will either delete or anonymize your personal information when we no longer have a legitimate business need to process it. If this is not feasible (for instance, because it is stored in backup archives), we will safely store your personal information and keep it separate from any additional processing until it can be deleted.

Legal Bases of Process Your Personal Information

We only process your personal information when we think it's required and we have a good reason (i.e., legal basis) to do so under the law that applies, such as when you give your consent, when we're following the law, when we're providing you with services to enter into or fulfill a contract, when we're protecting your rights, when we're pursuing legitimate business interests, or when we're protecting the public interest and some essential vital interests.

We will action your request within one month of receiving a request from you concerning any one of your rights as a Data Subject. When we are faced with an unusually large number of requests or particularly complicated requests, the time limit may be extended to a maximum of another two months. If we fail to meet these deadlines, we would, of course, prefer that you contact us to resolve the situation informally.

How we Transfer your Personal Data Internationally
