Occam Privacy Policy
Occam is an iPhone app built by Agent Science and Research. This policy explains exactly what the app collects, where it goes, and what we can and cannot see. It describes what the app actually does today, not what we might one day do.
An account is required
Occam requires you to sign in before you can use it, with Sign in with Apple or Sign in with Google. There is no anonymous or guest mode. This is a deliberate design choice rather than a growth tactic: a study represents months of your thinking, and without an account there is nowhere to keep it that survives the phone it was made on.
From your chosen provider we receive a user identifier, and your name and email address if you allow it. We use these to identify your account, restore your studies on a new device, and apply your subscription.
Your studies are backed up to our server
Your studies, meaning the problems, graphs, notes and experiments you create, are stored on your device and backed up to Occam's own server so that they survive a lost phone, a reinstall, or a move to a new device. They are held in our database, hosted on Railway, and linked to your account.
We want to be precise about what that means, because it matters: this backup is not end-to-end encrypted, so your study content is technically accessible to us. It is transmitted over an encrypted connection and stored in a private database, and we do not read it, sell it, share it, or use it to train AI models. But we will not claim we cannot see it when we can.
A separate, optional iCloud sync also keeps a snapshot of your analysis in your own iCloud account. That part we genuinely cannot read.
Cloud Reasoning
When you use a cloud AI feature, the relevant part of your graph and your prompt are sent to our server, which forwards them to Anthropic to generate a response. This content is not used to train any model. Once a request completes we keep no separate copy of it beyond the study itself.
On-device intelligence never leaves your phone. If you would rather nothing was sent anywhere, use only the on-device features.
Subscription and usage
We store whether you have an active subscription, the Apple transaction identifier needed to unlock your plan, and a count of the cloud runs you have used in the current period so we can apply your monthly allowance. Purchases are processed by Apple. We never see your payment details.
What Occam does not do
- No advertising, no ad networks, and no advertising identifiers
- No analytics or behavioural tracking SDKs
- No selling or sharing of personal data with third parties for their own use
- No cross-app or cross-site tracking
- Your study content is never used to train AI models
Service providers
These companies process data on our behalf, each for one specific purpose:
| Provider | What they do |
|---|---|
| Apple | Sign in with Apple, subscription processing, optional iCloud snapshot |
| Sign in with Google, when you choose that option | |
| Anthropic | AI generation for Cloud Reasoning features |
| Railway | Server and database hosting for accounts, study backup and the Cloud Reasoning API |
How long we keep things
Your studies stay until you delete them. Deleting a study removes it from your device and marks it deleted on the server, so it does not come back from another device. Usage counters reset each billing period. If you ask us to delete your account, we remove your account record and the studies backed up against it.
Your choices
- Use only on-device intelligence, so no study content is sent for processing
- Delete any study at any time
- Request deletion of your account and its backed-up studies by email
- Sign in with Apple and use Apple's private email relay if you would rather not share your address
Children
Occam is not directed at children under 13.
Changes to this policy
If this policy changes we will update the date at the top of this page and note anything material.
