License & Access

• Access to Callie is provided on a monthly subscription basis, beginning on the date the license is first validated within the application. Continued access beyond the subscription period requires renewal.

• License validation occurs locally within the application. Callie does not transmit EEG data or session content during license validation.

Supported Data & Compatibility

• Callie supports EDF and EDF+ EEG recordings generated by common clinical EEG and neurofeedback systems.

• Supported recordings must meet the following requirements:

  • Sampling rate between 128–512 Hz

  • Standard EEG channel configurations

  • Continuous recordings representing a single session

• Recordings with missing required channels, non-standard channel naming, corrupted files, or unsupported export configurations may not be compatible.

Recording Duration Requirements

• To ensure stable analysis:

  • Baseline recordings: Minimum duration: 60 seconds with a recommended structure of approximately 2-3 minutes total, including eyes-open and eyes-closed segments

• Activity/Session recordings

  • Minimum duration: 60 seconds

• Recordings shorter than these minimums may not contain sufficient data for reliable analysis and are not supported.

Processing & Data Handling

• All EEG data is processed locally on the user’s device. Callie does not upload, store, or transmit EEG recordings or derived neural data.

• Callie is intended for analysis of standard clinical session recordings and is not designed for continuous monitoring or diagnostic EEG studies.

Artifact Handling & Limitations

• Callie applies automated artifact detection and correction methods to reduce common sources of EEG noise, including motion, muscle activity, and channel instability.

• Analysis quality depends on the underlying signal quality. Recordings that are excessively noisy, unstable, or dominated by artifacts may produce limited results or fail analysis.

• Callie does not guarantee successful analysis for all EEG recordings.

Performance & System Requirements

• EEG session files may range from tens to several hundred megabytes. A minimum of 8 GB of system memory is recommended.

• Processing time varies by file size and system performance. Users should allow 30–60 seconds for application launch and EEG processing.

• Callie is currently supported on macOS running Apple Silicon processors (M1, M2, or later) and macOS 13 (Ventura) or newer. Intel-based Macs and Windows systems are not supported at this time.

Intended Use

• Callie is designed to provide supportive, non-diagnostic EEG-derived signal features for reflection, session review, and within person comparison. It is not a medical device and is not intended to diagnose, treat, or prevent any medical or psychiatric condition.

• All clinical interpretation and decision-making are performed independently by the licensed professional, without reliance on the software.

• Labels reflect changes relative to the individual’s baseline, not task difficulty or emotional effort.
