For example, we invest in artificial intelligence that uses machine learning to detect and block spam and malware, and to provide you with innovative features, like simultaneous translations. As part of this continual improvement, we sometimes add or remove features and functionalities, increase or decrease limits to our services, and start offering new services or stop offering old ones.</p> <p>We maintain a rigorous product research program, so before we change or stop offering a service, we carefully consider your interests as a user, your reasonable expectations, and the potential impact on you and others. We only change or stop offering services for valid reasons, such as to improve performance or security, to comply with law, to prevent illegal activities or abuse, to reflect technical developments, or because a feature or an entire service is no longer popular enough or economical to offer.</p> <p>If we make material changes that negatively impact your use of our services or if we stop offering a service, we’ll provide you with reasonable advance notice and an opportunity to export your content from your Google Account using Google Takeout, except in urgent situations such as preventing abuse, responding to legal requirements, or addressing security and operability issues.</p>
