How to use TenderApp safely

  • Use the business variant and sign a data processing agreement (DPA).
  • Do not enter unnecessary personal data into prompts; anonymise where possible.
  • Enable EU data residency where the provider offers it.
  • Keep a professional in the loop: prospect data remains personal data; cold outreach with AI must still comply with the GDPR and the anti-spam rules.

In the third quarter of 2026, OpenAI made more than 200 reports to law enforcement about threatened violence based on ChatGPT conversations. Conversations in which someone appears fixated on violence may be ended automatically by ChatGPT, and if it happens repeatedly, OpenAI can pause the account. So don't assume that what you type into ChatGPT stays confidential. source

ChatGPT can use plugins to search and summarise iCloud mail and change appointments, including on the free subscription. Signing in uses an app-specific password from Apple; it remains valid if you disconnect the integration in ChatGPT and you must revoke it yourself via account.apple.com. source
