Privacy Policy

01

Introduction

Lost Arrow Studios, LLC ("Company," "we," "us," or "our") operates the Digamo mobile application (the "App"). This Privacy Policy explains our data practices. Please read it carefully. By using the App, you agree to the practices described herein.

02

Information We Collect

2.1 — What We Do NOT Collect

Digamo does not collect the following:

• Your voice or audio — speech recognition runs entirely on your device using Apple's built-in speech recognition APIs
• Your conversations — all dialogue with your AI language partner is processed on-device and is not transmitted to our servers
• Your learner profile — your progress, vocabulary gaps, grammar patterns, and learning history are stored on your device only
• Your name, email address, or any account information — Digamo does not require an account
• Your location
• Device identifiers, hardware IDs, or advertising identifiers
• Usage analytics or behavioral data
• Payment or financial information — all purchases are handled entirely by Apple

2.2 — What We Do Collect

Digamo does not collect conversation content, voice data, learner profiles, or personal account information. The only data associated with your use of the App flows through Apple's own systems:

• Subscription status: Your subscription is managed entirely by Apple via StoreKit. We receive only a confirmation that a valid subscription exists — not your payment details, Apple ID, or any personal information. This confirmation is verified locally on your device using Apple's APIs.
• Model download: On first launch, the App downloads the AI language model (Gemma) from a content delivery server. The text-to-speech voices are included in the App itself and are never downloaded separately. This download is anonymous — no account or identity is associated with it. Your IP address may be visible to our CDN provider during the download, as is standard for any internet download. After the initial download, the App operates entirely offline.

2.3 — On-Device Storage

The following data is stored locally on your device and never transmitted:

• Conversation history (text only, no audio)
• Learner profile — inferred observations about your vocabulary, grammar patterns, and progress
• Language and partner preferences
• A boolean flag confirming you have passed the age verification screen during onboarding

All on-device data is deleted when you delete the App.

03

Local Processing Architecture

Digamo is built on a local-first architecture. The following components all run entirely on your device:

• Speech recognition (STT): Your voice is transcribed on-device using Apple's SpeechTranscriber API. Audio never leaves your device.
• AI inference: Conversation responses are generated on your device by Gemma, an open model published by Google, running via Apple's MLX framework. Gemma runs entirely on your device: nothing you say or type is sent to Google, to us, or to any other service. Google states that it claims no rights in the text the model generates.
• Text-to-speech (TTS): Responses are spoken aloud using Kokoro voice models, which ship inside the App and run entirely on your device.
• Learner modeling: Your vocabulary gaps, grammar patterns, and progress observations are inferred and stored locally. This profile is never transmitted.
• Conversation history: Session text is stored locally on your device only. It is not backed up to our infrastructure.

This architecture means that a network connection is not required for normal use after the initial model download. It also means we are technically unable to access, review, or transmit your conversations — not as a matter of policy, but as a matter of design.

04

Age Verification

Digamo is intended only for users age 17 and older. Apple enforces this restriction via the App's 17+ App Store rating. During onboarding, you must confirm you meet the minimum age requirement. The date of birth you enter is evaluated locally on your device and is immediately discarded — it is never stored or transmitted. Only a boolean confirmation flag is retained on your device.

We do not knowingly collect information from users under 17. If you believe a child has used the App in violation of this policy, please contact us at support@digamo.ai.

05

Model Download

The AI language model (Gemma) is downloaded to your device on first launch. It is large and downloaded once; it does not need to be downloaded again unless you reinstall the App. Voice files are part of the App and are never downloaded separately.

During the model download:

• Your IP address is visible to our content delivery network provider, Cloudflare (R2), as is standard for any internet download. Cloudflare's privacy policy is available at cloudflare.com/privacypolicy.
• No account, identity, or personal information is associated with the download request
• We do not enable request log retention for the model download. Download activity is not retained by us beyond what is necessary for CDN operation.

Digamo is designed to operate offline after the required download is complete. No further requests are made to our infrastructure during normal use.

06

Subscriptions and Payments

Digamo subscriptions are purchased and managed entirely through the Apple App Store. Apple handles all payment processing. We do not receive, store, or process your payment card information, Apple ID, or any other financial or identity data.

We do not operate backend systems that receive subscription or usage data. Subscription status is validated entirely on-device via Apple's StoreKit APIs.

To cancel your subscription, manage your subscription through your iPhone Settings → Apple Account → Subscriptions, or through the App Store app.

07

Third-Party Services

Digamo does not currently use third-party analytics SDKs, advertising networks, crash reporting services, or behavioral tracking tools. This includes code from Facebook, Google Analytics, Firebase, Amplitude, Mixpanel, Sentry, and similar services.

The only third-party relationship relevant to your privacy is Apple's App Store, which manages subscription purchases and delivery of the App in accordance with Apple's privacy policy at apple.com/legal/privacy.

08

Data Security

Because Digamo processes all data on your device and transmits nothing to external servers during normal use, the security of your data is governed by your device's own security model — iOS file protection, app sandboxing, and your device passcode or biometric authentication.

We recommend keeping your device software up to date and using a strong passcode. Deleting the App removes all Digamo data from your device.

09

Data Deletion

To delete all Digamo data from your device, delete the App. This removes all conversation history, your learner profile, preferences, and the age verification flag. The AI model is also deleted.

To cancel your subscription, do so through your iPhone Settings before deleting the App to avoid future charges. Subscription cancellation and any refund requests are handled by Apple.

Because we hold no personal data on our servers, there is no server-side data to request deletion of. If you have questions, contact us at support@digamo.ai.

10

Your Privacy Rights

Because Digamo is designed to avoid collecting personal information, many privacy rights requests may not apply in practice. We do not sell personal information, create advertising profiles, or share data with third parties.

10.1 — California Residents (CCPA/CPRA)

10.2 — EEA, UK, and Switzerland (GDPR)

Changes to This Privacy Policy

We may update this Privacy Policy from time to time. We will notify you of material changes via an in-app notification. The "Last Updated" date at the top of this policy reflects the most recent revision. Your continued use of the App after changes take effect constitutes acceptance of the revised policy.
