Your words are yours.
MountainRiver is a private journal. Because what you write here can be among the most personal things you'll ever put into words — relationships, health, work, money, fear, hope — we've built the product so that your writing stays yours. This page explains, plainly, what happens to it.
Who we are
MountainRiver is operated by Tommy Duncan. We are the data controller for your information. For any privacy question, contact us at hello@mountainriver.app.
(MountainRiver is in the process of being established as a company. When that is complete, this section will be updated to name the company as controller; the way your data is handled will not change.)
What we collect
- What you write — your entries, reflections, decisions, themes, goals, and the routes you chart. This is stored so the app can show it back to you, and for no other purpose.
- Your account — the email address you sign in with.
- Minimal technical data — a count of AI requests per account, used only to prevent abuse. We run no third-party analytics and no advertising trackers.
We do not collect your contacts, your location, tracking identifiers, or any behavioural profile.
Where it's stored
Your data is stored with our infrastructure provider, Supabase, on servers in the European Union (Ireland). Access controls at the database level mean each account can reach only its own data.
Who can see your writing
No human at MountainRiver reads your entries. We have not built — and do not have — any tool or process that shows the contents of your journal to us or to anyone else. Your writing is not reviewed, human-moderated, or handed to any third party for their own purposes.
When AI is involved
MountainRiver offers AI reflections — to help you think through a decision, understand a relationship, or map a path to a goal. This happens only when you ask for it. Writing that you simply capture, and never reflect on, is never sent anywhere for AI.
When you do ask for a reflection:
- The words you bring are sent to Anthropic PBC (the company behind the Claude AI), which performs the analysis and returns it immediately, on the same connection.
- No name, email, account ID, or other identifier is attached to your writing when it is sent. Anthropic receives the text you brought and nothing that identifies you within MountainRiver. (Please note: if you write a person's name in an entry, that name is part of the text you wrote — we remove the account identity around your writing, not the content of the writing itself.)
- Under Anthropic's API terms, your writing is not used to train Anthropic's AI models. MountainRiver does not train any models of its own on your writing either.
- Anthropic may retain API content briefly for operational and safety purposes before deletion, per their published API policies. It is not used for training.
We use AI as a tool that works for you, in the moment you ask — never as a way to mine what you write.
Deleting your data
You can permanently delete everything — all of your writing and your account — at any time from Settings. When you do, we hard-delete your data record and your account from our systems. This is not a hide or a soft-delete, and it cannot be recovered. You can export your writing before deleting if you'd like to keep a copy.
Your rights
If you are in the EU/EEA or a comparable regime, you have the right to access, correct, export, and delete your data, and to object to or restrict processing. Because export and deletion are built into the app, you can exercise most of these yourself, instantly. For anything else, contact hello@mountainriver.app. Our lawful basis for processing your writing is performing the service you've asked us to provide; for AI reflection specifically, we rely on your explicit consent, which you give before the first reflection and can withdraw by simply not using it.
Age
MountainRiver is intended for adults. You must be 18 or older to use it. Given the intimate nature of a journal and the involvement of AI, we've deliberately made this an adults-only product, and we do not knowingly collect data from anyone under 18.
Changes
If we change how your data is handled in any material way — especially anything involving AI processing — we will update this page and, where the change is significant, ask for your consent again in the app.
