Data retention policy
Effective Date: 05/31/2018
Some data you can delete whenever you like, some data is deleted automatically, and some data we retain for longer periods of time when necessary. When you delete data, we follow a deletion policy to make sure that your data is safely and completely removed from our servers or retained only in anonymized form.
Information retained until you remove it
We offer a range of services that allow you to correct or delete data stored in your account. For example, you can:
- Edit your personal info
- Delete your account entirely, including your content like comments and questions
We’ll keep this data in your account until you choose to remove it. And if you use our services without signing in, we also offer you the ability to delete some information linked to what you use to access our services, like a device, browser or app.
Data that expires after a specific period of time
In some cases, rather than provide a way to delete data, we store it for a predetermined period of time. For each type of data, we set retention timeframes based on the reason for its collection. For example, to ensure that our services display properly on many different types of devices, we may retain browser width and height for up to 9 months. We also take steps to anonymize certain data within set time periods.
Information retained until your account is deleted
We keep some data for the life of your account if it’s useful for helping us understand how users interact with our services and how we can improve them.
Information retained for extended time periods for limited purposes
Sometimes business and legal requirements oblige us to retain certain information, for specific purposes, for an extended period of time. Reasons we might retain some data for longer periods of time include:
- Security, fraud & abuse prevention. To protect you, other people, and Mobile application from fraud, abuse, and unauthorized access. For example, when we suspect someone is committing ad fraud.
- Complying with legal or regulatory requirements. To meet any applicable law, regulation, legal process or enforceable governmental request, or is required to enforce applicable Terms of Service, including investigation of potential violations. For example, if we receive a lawful subpoena.
Enabling safe and complete deletion
When you delete data in your account, we immediately start the process of removing it from the product and our systems. First, we aim to immediately remove it from view and the data may no longer be used to personalize your Mobile application experience.
We then begin a process designed to safely and completely delete the data from our storage systems. Safe deletion is important to protect our users and customers from accidental data loss. Complete deletion of data from our servers is equally important for users’ peace of mind. This process generally takes around 3 months from the time of deletion. This often includes up to 7-days recovery period in case the data was removed unintentionally.
Each Mobile application storage system from which data gets deleted has its own detailed process for safe and complete deletion. This might involve repeated passes through the system to confirm all data has been deleted, or brief delays to allow for recovery from mistakes. As a result, deletion could sometimes take longer when extra time is needed to safely and completely delete the data. Our services also use encrypted backup storage as another layer of protection to help recover from potential disasters. Data can remain on these systems for up to 6 months.
As with any deletion process, things like routine maintenance, unexpected outages, bugs, or failures in our protocols may cause delays in the processes and timeframes defined in this article. We maintain systems designed to detect and remediate such issues.
