Privacy Policy

Effective October 23, 2026

This policy explains what Hyde ("we", "us") collects when you use the Hyde app on iPhone and iPad and this website, how we collect it, every way it's used, who it's shared with, and the choices you have. If anything here is unclear, email hyde@haydenkong.com.

What we collect, how, and why

Hyde only uses your information to run the app for you. Here is everything it handles.

Messages and what you tell Hyde

• What: what you type, your chat history, things Hyde remembers about you, your goals and ideas, and the topics you pick for your Feed.
• How: you enter it in the app.
• Why: so Hyde can reply, remember context, plan check-ins and put together your Feed and Ideas.
• Where it goes: stored on your device. Sent to OpenAI to write replies, only after you allow it.

Photos, files and voice

• What: photos and files you send, voice notes, your voice during calls and Listen In, and transcripts of them.
• How: you choose to send them, or you start a call, voice note or Listen In and speak.
• Why: so Hyde can see, hear and transcribe what you share and respond to it.
• Where it goes: stored on your device. Sent to OpenAI to understand and reply, only after you allow it. Calls connect directly from your device to OpenAI.

Your name

• What: your first name.
• How: from Sign in with Apple if you choose to share it, or from what you tell Hyde.
• Why: so Hyde knows what to call you.
• Where it goes: stored on your device and included with what Hyde sends to OpenAI.

Calendar, reminders and contacts

• What: the events, reminders and contact details Hyde looks up, and the upcoming events it uses to plan your Feed.
• How: read from your device, only if you've given Hyde access in the iOS permission prompt, and only when you ask or when your Feed is being prepared.
• Why: to answer questions about your plans, add events or reminders you approve, find someone's details for a draft, and fit your Feed around your day.
• Where it goes: the details needed for your request are sent to OpenAI to write the reply. Hyde asks you to approve anything it adds to your calendar or reminders.

Location

• What: where your device is, only while you're using the app.
• How: from your device's location services, if you allow it.
• Why: for weather and answers about places near you.
• Where it goes: sent to OpenAI with your question, and to Open-Meteo when you ask about the weather.

Identifiers

• What: the random identifier Apple gives us for your account (it's unique to Hyde), and an anonymous identifier derived from it.
• How: created when you sign in with Apple.
• Why: to keep you signed in and to stop misuse. The anonymous identifier goes to OpenAI with each request, so OpenAI can stop abuse by one person without knowing who they are.

Reports and technical logs

• Reports: if you report something Hyde said, the app sends us that message, the reason you picked and the anonymous identifier, so a person can review it.
• Logs: our server's host, Cloudflare, keeps short-lived technical logs, like the time of a request, whether it worked and roughly where it came from, to keep Hyde running and secure. They never include what you said.

Sharing with OpenAI

Hyde's replies, voice, images and calls are made by AI models from OpenAI, a third-party AI company. So that you can decide for yourself, Hyde asks before it shares anything:

• Your permission comes first. When you first open Hyde, the "before we chat" screen explains that Hyde is powered by OpenAI and lists what it shares with OpenAI. Nothing is sent to OpenAI until you tap Allow and continue. If you tap Not now, nothing is shared and Hyde won't reply until you change your mind.
• You can stop anytime. In Hyde, tap Hyde's picture at the top of any screen, tap Settings (the gear), then Data sharing and Stop sharing. Nothing more is sent until you turn it back on.
• We'll ask again before Hyde starts sharing anything new.

Once you allow it, the app sends OpenAI what it needs to respond, which can include:

• your messages, and recent conversation history for context
• photos, files and voice notes you send
• your voice during calls and Listen In (calls connect directly from your device to OpenAI)
• what Hyde remembers about you, your goals, your Feed topics, your name, city and time zone
• if you've allowed access, details Hyde looks up for you, like calendar events, reminders, contacts or your location, and your upcoming events so your Feed fits your day
• web searches Hyde runs to answer you or to put together your Feed

OpenAI processes this only to provide its service to us. Under OpenAI's API data controls, it isn't used to train OpenAI's models. OpenAI keeps it for up to 30 days, so Hyde can finish a reply after you close the app and so OpenAI can spot abuse, and then deletes it unless the law requires otherwise.

We don't read your conversations. The only exception would be investigating serious abuse, or helping with a problem you've asked us to look into.

What our server sees

The app talks to OpenAI through Hyde's server at hyde.haydenkong.com, which runs on Cloudflare. It checks that you're signed in, adds our OpenAI access key, and passes requests through as they happen. It doesn't store your messages, photos or voice. Technical logs are deleted within 7 days.

Sign in with Apple

You sign in with your Apple Account. Apple gives us a random identifier that's unique to Hyde, which we use to keep you signed in and to limit abuse. Hyde doesn't ask Apple for your email address. If you choose to share your first name, Hyde keeps it on your device and includes it with what it sends to OpenAI, so it knows what to call you.

Permissions

Hyde only asks for access when you use a feature that needs it, and you can change any of these in your device's Settings app. When Hyde uses something you've given it access to, the details it needs are sent to OpenAI as described above.

• Microphone for calls, voice notes and Listen In.
• Camera and Photos to share pictures with Hyde and save images it makes.
• Calendars and Reminders to check your schedule, add events or reminders when you ask (Hyde asks you to approve each one), and plan your Feed around your day.
• Contacts to look someone up when you ask.
• Location for weather and places near you, only while you're using the app.
• Notifications for Hyde's texts and check-ins. These are scheduled on your device.

Who we share data with

We share data only with these providers, only for the purposes below:

• OpenAI, which writes Hyde's replies, voice, images and transcripts, with your permission, as described above.
• Cloudflare, which hosts Hyde's server and this website.
• Apple, for Sign in with Apple.
• Open-Meteo, which gets your location, or the place you asked about, when you ask about the weather.
• Services you connect to Hyde, which receive the requests needed to do what you ask. Their own privacy policies apply, and you can remove a connection at any time.

Each of these providers protects your data with the same or equal protection as this policy: they may use it only to provide their service, must keep it confidential and secure, and may not sell it or use it for advertising. OpenAI processes data as our service provider under its business terms for the API, which limit it to providing and securing its services and rule out training on your data.

When Hyde shows you a link or a photo from a website, your device loads it directly from that site, which will see your IP address like any website you visit.

What we don't do

• We don't sell or rent your data, or share it for advertising.
• We don't track you across other apps or websites, and Hyde has no ads.
• We don't use third-party analytics in the app.
• This website doesn't use cookies.

How long data is kept, and deleting it

• Everything Hyde stores on your device stays until you delete it or the app. Like other app data, it can be included in your device backups, depending on your backup settings.
• OpenAI keeps what Hyde sent for up to 30 days, then deletes it.
• Our server's technical logs are deleted within 7 days. We keep reports only as long as we need to look into them.

To delete your account, tap Hyde's picture at the top of any screen, tap Settings (the gear), then Delete account. This erases everything Hyde stored on your device, signs you out, and removes Hyde from Sign in with Apple. Deleting the app also removes its data from your device. You can also stop using Sign in with Apple with Hyde in your device's Settings, under your name, then Sign in with Apple.

Children

Hyde isn't meant for children under 13, or the minimum age in your country if that's higher. We don't knowingly collect information from children. If you think a child has used Hyde, contact us and we'll help.

Your rights

Depending on where you live, you may have the right to access, correct, delete or move your personal information, to object to how it's used, or to withdraw your consent. Because almost everything lives on your device, you can see and delete it right in the app, and you can withdraw your consent to sharing with OpenAI in Settings at any time. For anything else, email us and we'll respond within 30 days.

Security and where data is processed

Everything Hyde sends travels over encrypted connections. Your sign-in is kept in your device's Keychain, and our OpenAI access key never leaves our server. Cloudflare and OpenAI may process data in the United States and other countries. No system is perfectly secure, but we work to protect your information.

Changes

If we change this policy, we'll update the date at the top. If a change is significant, we'll let you know in the app before it takes effect, and if Hyde would share something new with OpenAI, it will ask for your permission again.
