Who else handles it
- Base44 (run by Wix.com Ltd) hosts the app and its database. It stores Switch's data in the United States and protects transfers from the UK with the safeguards in its data processing terms.
- AI training: Base44's privacy page says that, on Switch's current plan, data in the app may be used to train its AI models. I'll update this policy once Base44 confirms what it uses.
- The AI companies behind Period Buddy receive your messages to write replies. Base44 works with companies such as Anthropic, Google and OpenAI, mostly in the United States. Base44's full list.
- Google stores quiz answers in a Google Sheet.
- Brands never get your data from me. If you click through to a brand, its own privacy policy applies.
I never sell your data.
How long I keep it
- Your account, products, period dates and chats: until you delete them, or 24 months after you last sign in. I'll email you a month before deleting.
- Questions sent to me: until they're answered and added to Period Buddy, and no longer than 12 months.
- Talk to Elise messages: 12 months after I reply.
- Feedback: 24 months.
- Quiz answers in the Google Sheet: 24 months.
- Guest chats: not saved.
Your rights
You can see, correct or delete your data, and change any tick in Settings. You can take back your consent at any time.
- Delete my data removes your profile, cycle logs, chats and feedback.
- Delete my account removes your account and everything in it.
- For a copy of your data, email me at elisedarras@outlook.com and I'll send it within one month.
If you're unhappy with how I handle your data, you can complain to the Information Commissioner's Office (ico.org.uk).
Under-18s
Switch accounts and Period Buddy are for people aged 18 and over. If you're under 18, you can still use Quick help and the Cycle tab without an account. Everything stays on your phone. If I find out someone under 18 has an account, I'll delete it.
Changes
If this policy changes, I'll tell you in the app.
