Summary
Multitac does not require a Multitac account or upload your notebooks to a Multitac server. Calculations run on your device. Memory is stored locally. When on-device Insights are available, notebook excerpts are processed by Apple’s on-device model without a cloud AI fallback.
Documents
Your TAC documents are files you create, open, and save. They remain under your control. If you save a document in iCloud Drive, Apple syncs that file according to your Apple Account and iCloud settings. Multitac does not operate a separate document sync service.
Memory
Memory Review proposes useful thoughts and calculated Results from TACs opened on the current device. Pending candidates record their TAC and source line but cannot influence Memory search, TIQs, or Insights until you approve them.
- Memory does not crawl unrelated files or unopened iCloud documents.
- Equivalent candidates may be grouped while retaining their contributing source references.
- You can edit proposed wording, approve or dismiss candidates, exclude a TAC, forget approved items, pause learning, or clear all local Memory.
- The local Memory Review and approved Memory index are not embedded in your TAC documents or synced by Multitac.
Insights and TIQs
Where supported, Multitac uses Apple’s on-device Foundation Model for reviewed, open-ended TIQ proposals and optional Insights. Guided, curated, and Personalization TIQs do not use a language model. The model receives a bounded selection of source text and calculated results. Multitac validates returned source references before display, but a valid reference does not prove the generated interpretation is correct.
Model-driven TIQ history and pending proposals may be stored in the TAC document. Kept and permanently dismissed Insight records are stored locally in app preferences. Other unkept suggestions are temporary. Multitac does not send this material to an external AI provider and has no cloud AI fallback.
Local app records
Before the first model-driven TIQ or Insight, Multitac shows an AI limitations notice. If you continue, the app stores a local receipt containing the notice version, acknowledgement date, app version, build number, and a digest of the notice text. It does not contain your name, email, Apple ID, device identifier, IP address, advertising identifier, or a generated fingerprint. Clearing app preferences or reinstalling the app may remove the receipt and cause the notice to appear again.
You can remove Memory through its controls, remove kept or hidden Insight history through the app, and remove TIQ history by editing or deleting the relevant TAC. Deleting app preferences or the app removes locally stored preferences, subject to operating-system backup and restoration behavior. TAC files remain wherever you chose to store them until you delete them there.
Diagnostics and analytics
The Multitac app does not operate its own analytics, advertising, or tracking system. Apple may provide App Store, crash, or diagnostic information under your device settings and Apple’s privacy policies. Any future telemetry added to the app will be described here before collection begins.
