Privacy Policy

Modelbase · Effective date: 5 October 2026

Modelbase is an app for iPhone, iPad and Mac that runs AI models on your device. This policy explains what happens to your information when you use it. “We” means Alisher Akhmedzhanov, the developer of Modelbase.

In short

• We do not collect, receive or store your chats or any personal information. Modelbase has no account, no analytics, no advertising and no tracking.
• When you chat with a model that runs on your device, your messages are processed on your device.
• Information leaves your device only in the cases listed below, and it goes to the service named there, not to us.

Information that stays on your device

Modelbase keeps the following in its own storage on your device:

• your chats, including the photos and documents you attach;
• the assistant’s instructions and the memories you ask it to keep;
• your settings and usage statistics (counts of replies and tokens);
• the AI models you download (one comes with the app).

You can delete a chat at any time, erase everything in Settings > Storage > Erase All Data, or delete the app.

Modelbase asks for these permissions only when you use the feature that needs them:

• Microphone and Speech Recognition, for dictation and voice mode. Your speech is turned into text on your device. If you turn on “Allow online dictation”, Apple’s speech service processes the audio instead.
• Camera and Photos, to attach a photo you take or choose, or to save an image you share from a chat.
• Location, only when you ask about places near you and allow it.
• Calendar and Reminders, read on your device to answer your questions about them.
• Local Network, to reach a model server you added on your own network.

When information leaves your device

iCloud sync. If you use iCloud, Modelbase syncs your chats, memories, settings, usage statistics and the list of providers you connected through your own private iCloud storage, and keeps your provider keys in iCloud Keychain, so they are the same on your devices. Apple stores this data under your Apple Account; we cannot access it. You can turn sync off in Settings > Chats.

Looking things up. When a reply uses web search or another lookup, your device sends what it is looking for directly to the service that answers:

• web search: DuckDuckGo, and the websites whose pages are opened to answer you;
• reference sources: Wikipedia, Wikidata, Stack Exchange, Google News and OpenStreetMap;
• weather: Open-Meteo (the place you ask about, or your coordinates if you allowed location);
• market data: Yahoo Finance, Stooq, Frankfurter and CoinGecko (the symbol or currency you ask about);
• places and transit: Apple Maps.

These services receive the query and, as with any internet request, your IP address. Modelbase sends them no account or identifier of ours. You can turn web search and each tool off in Settings.

Problem reports. If you choose Report a Problem, Modelbase prepares an email to us in your own mail app. It holds what you wrote, the app’s version, your device model and system version and, if you leave “Include this exchange” on, your question, the reply and the technical log of how the reply was made. Saved memories, photos, files and keys are left out. You can read the whole report before it goes, and nothing is sent unless you send the email yourself.

Providers you connect. Modelbase lets you connect OpenRouter with your own key, or a model server of your own. When you chat with a model from such a provider, your device sends it your messages, the relevant chat history, the assistant’s instructions, the content of your attachments and the results of lookups made for the reply (which can include calendar, reminder or location information you asked about). This goes directly from your device to that provider and is governed by its terms and privacy policy (for OpenRouter: openrouter.ai/privacy, and the policy of the company that runs the model). Your keys are stored in the Keychain on your device.

Model downloads. Models are downloaded from Hugging Face, which sees your IP address and which model you download.

Images in answers. Site icons and images shown in answers are loaded from the web (DuckDuckGo’s icon service and the sites themselves).

Apple. Your download of the app is handled by the App Store. If you chose to share analytics with app developers in your device’s settings, Apple may give us aggregated, anonymous statistics about installs and crashes. They do not identify you and never include your chats.

What we do not do

• We do not sell or share your information.
• We do not show ads or track you across apps and websites.
• We do not use your chats to train models. We never receive them.

Children

Modelbase is not directed at children under 13 (or the minimum age in your country). We do not knowingly collect information from children; we collect none from anyone.

Your rights

Because we hold no personal information about you, there is nothing for us to provide, correct or delete. The data on your device and in your iCloud is under your control, as described above. For data held by a service you used through the app (for example OpenRouter), contact that service. If you are in the European Economic Area or the United Kingdom you also have the right to complain to your data protection authority.

Changes to this policy

If we change this policy we will update this page and its effective date. If a future version of Modelbase offers features that process information on our servers, this policy will say so before those features are available.
