Ziflow's public URLs to proofs are typically not crawled or indexed by Google Search by default. Ziflow employs measures such as robots.txt directives and meta tags to prevent search engine indexing of publicly shared proofs.

However, it's essential to note that search engine behavior and policies can change over time. While Ziflow takes steps to prevent indexing, it's still a good practice to exercise caution when sharing sensitive or confidential information via public URLs. Additionally, always review and adhere to Ziflow's privacy and security settings to ensure the protection of your data.
