Last updated October 30, 2026. This covers the Thought Monitor beta.
Thought Monitor is an app that asks you, about ten times a day, what you are thinking. You write or say the thought, confirm how it felt, and over a week the app shows you your own patterns. It is made by Mizar Media LLC. When this page says "we", it means Mizar Media and the people building the app.
The short version: we collect what the app needs to work and nothing else. We don't sell your data, we don't show ads, and there is no tracking or analytics code in the app. Nobody here reads your thoughts.
| What | Why | How long we keep it |
|---|---|---|
| Your email address | To sign you in with a code and to send you account emails, such as a deletion receipt | While you have an account, plus 30 days |
| The thoughts you write or dictate | So you can read them back in your notebook and export them. Stored encrypted with a key that belongs to your account | While you have an account |
| The feeling for each entry (for example "stressed, a kind of fear") and what the app suggested before you answered | To build your report and to measure how well the app's word list guesses | While you have an account |
| When each entry was made, your time zone, and the place you picked (Home, Work, Car, or a name you type) | To show you when and where feelings show up. Place names you type are encrypted like your thoughts | While you have an account |
| Your ping hours | To send pings only inside the ten hours you chose | While you have an account |
| A push token for each phone you sign in on | To make your phone buzz. The notification carries a short question, never anything you wrote | Until you sign out, delete the app, or 90 days after the token stops working |
| Delivery records for each ping and whether it was answered | To check that pings arrive on time | 90 days |
| Your consent choices | To prove what you agreed to and when | 6 years, even after your account is deleted |
| Security and error records (failed sign-ins, IP addresses, crash details with any personal text removed) | To keep accounts safe and fix bugs | 30 to 90 days |
| Bug reports you send from the app | To fix what you reported. They never include your thoughts | Deleted once handled, and never kept longer than 30 days |
We do not collect your location from GPS, your contacts, your calendar, your photos or who you were with. The app does not ask for those permissions.
The app reads your thought on your phone, with a word list built into the app, and suggests a feeling. You confirm it or pick another. No AI service reads your thought, on your phone or on our servers.
If you dictate, the speech is turned into text by your phone's own keyboard microphone, the same one you use for texting. How your phone handles that is covered by Apple's or Google's privacy policy. We receive only the text.
Nobody here reads your thoughts. There is no admin screen, no support tool and no search that shows them to us.
We also want to be straight about the limit of that. Your thoughts are encrypted with a key that belongs to your account, and our servers hold the key that unlocks your key. That is what lets you get your writing back on a new phone. So it would be technically possible for us to decrypt them. Nothing in the product does, and if that ever changes, this page changes first.
During sign-up you can say yes or no to research. If you say yes, patterns from your entries may later be combined with other people's to study how feelings show up in everyday thinking. Research only ever uses combined numbers, never your thought text, your name or your email, and no group smaller than ten people is shown. Saying no changes nothing about the app. You can turn it off in Settings at any time. From then on your entries stay out, but numbers already published can't be taken back. No research has been run yet.
We never sell your data or share it for advertising. These companies help run the app and only receive what they need:
| Company | What they do | What they receive |
|---|---|---|
| Cloudflare | Carries traffic between the app and our servers and protects them from attacks | Everything the app sends on its way to our servers, including entries, and IP addresses. Cloudflare passes it through and does not keep or use it |
| Postmark (ActiveCampaign) | Sends sign-in codes and account emails | Your email address and the email itself. Emails never contain your thoughts, feelings or report numbers |
| Apple Push Notification service and Google Firebase Cloud Messaging | Make your phone buzz | Your phone's push token and the short ping question |
| Expo | Builds and signs the app | Our source code, never your data |
We would share data with the police or a court only if the law requires it.
On servers in the United States. Encrypted backups are kept for 30 days.
These work the same for everyone, wherever you live. If you live in Washington, Nevada or another state with a consumer health data law, our Consumer Health Data Privacy Policy lists what that law asks us to tell you. If something here doesn't work for you, write to us and we will answer within 30 days.
Thought Monitor is for adults. It is not meant for anyone under 18, and we don't knowingly collect data from children. If you think a child has signed up, write to us and we will delete the account.
If something you write sounds like you might be in danger, the app shows a way to reach the 988 Suicide and Crisis Lifeline. That check happens on your phone. We are not told it happened.
If we change this policy, we will update the date at the top. If a change affects how your existing data is used, we will tell you in the app or by email before it takes effect.
