ECHO Privacy Policy

Effective date: August 5, 2026
Policy version: 1.0

This Privacy Policy explains how 3Nsofts ("3Nsofts," "we," "us," or "our") handles information when you use ECHO Survival AI ("ECHO" or the "App"). ECHO is designed to work locally and offline. We do not operate an ECHO account system, advertising network, or analytics service.

1. Information ECHO handles

Information you enter

ECHO may store your conversations and optional profile details, including experience level, environment, equipment, allergies, medical considerations, or physical limitations you choose to provide. This information is stored locally on your device so ECHO can display conversation history and, when enabled, adapt responses.

Do not enter information about another person unless you have permission and it is necessary for the immediate situation.

Location and environmental sensors

If you grant permission, ECHO may use precise location, compass heading, motion, barometer, relative altitude, and related sensor readings to display coordinates, estimate terrain movement, record a breadcrumb trail, and save places such as camp or a vehicle. This information is processed and stored locally. ECHO does not automatically transmit it to 3Nsofts. It leaves your device only when you deliberately use an Apple sharing feature.

Microphone and speech recognition

If you grant permission and activate voice input, ECHO temporarily processes microphone audio to convert speech to text. ECHO requests Apple's on-device speech-recognition mode. ECHO does not retain the audio recording after the recognition session or send it to a 3Nsofts server. Availability and behavior of Apple's system frameworks remain subject to Apple's software and policies.

Purchases

Apple processes App Store purchases. ECHO receives limited transaction and entitlement information needed to unlock purchased functionality and restore purchases. We do not receive your full payment-card details. Apple's handling of purchase information is governed by Apple's privacy policy.

Downloads and ordinary network information

ECHO may connect to 3Nsofts or its infrastructure providers to download the offline AI model, knowledge updates, or other app resources. Like most internet services, the download provider may temporarily process ordinary connection and security information such as IP address, request time, requested file, device/app user-agent, response status, and transfer size. This information is used to deliver files, maintain reliability, prevent abuse, and investigate security incidents. It is not used by ECHO for behavioral advertising or cross-app tracking.

2. How information is used

ECHO uses information only to:

  • provide conversations, emergency guides, navigation, speech input, and saved history;
  • personalize responses when you enable profile learning;
  • verify purchases and downloaded resources;
  • maintain security, reliability, and legal compliance; and
  • respond when you contact 3Nsofts for support.

We do not sell personal information. We do not share it for cross-context behavioral advertising. ECHO contains no third-party advertising SDK or third-party analytics SDK.

3. Where information is stored

Chats, profiles, settings, acknowledgement records, saved locations, breadcrumb trails, and downloaded models are stored on your device using Apple platform storage. ECHO's app database is configured without CloudKit synchronization. Your own device backups may include app data depending on your Apple backup settings; those backups are controlled by you and Apple.

4. Service providers and external services

Limited information may be processed by:

  • Apple, for App Store distribution, purchases, operating-system permissions, sharing, and system frameworks;
  • download and hosting providers, including infrastructure used to deliver ECHO model and knowledge files; and
  • support providers, only if you choose to contact us and provide information.

These providers process information under their own terms and privacy obligations. External websites opened from ECHO have their own privacy policies. Independent safety-reference organizations linked in the App do not sponsor, endorse, or review ECHO.

5. Retention and deletion

Local app data remains until you delete it through ECHO's controls, reset the relevant feature, or delete the App. Model updates may remove superseded model files after a replacement is verified. You can disable profile learning, clear learned profile details, delete chats, clear saved navigation information, revoke permissions in iOS Settings, or delete ECHO to remove its local container.

Download-host security logs, if created, are retained only as reasonably necessary for delivery, abuse prevention, security, and legal obligations according to the provider's configured retention practices.

Because 3Nsofts does not receive your locally stored ECHO data, we generally cannot access, recover, export, or delete that data for you.

6. Health and sensitive information

Information about injuries, symptoms, allergies, or medical considerations may be sensitive. ECHO processes user prompts locally for on-device guidance. ECHO is not a medical-record service, health-care provider, or substitute for professional care. Do not use ECHO as your only repository for information needed in an emergency.

ECHO does not use HealthKit and does not claim that HIPAA applies to locally stored consumer app data. Other privacy and consumer-protection laws may apply depending on your location and how you use the App.

7. Security

We use the privacy and security protections available through iOS, local processing, download integrity verification, and minimal network access. No storage or transmission method is guaranteed to be completely secure. Protect your device with a passcode, install operating-system updates, and avoid sharing sensitive transcripts or coordinates unless necessary.

8. Children

ECHO is not directed to children under 13. A child or minor should use ECHO only with a parent or legal guardian where required by law. Do not submit a child's personal or health information unless necessary, permitted by law, and appropriately supervised.

9. Your choices and rights

Depending on where you live, you may have rights regarding personal information, including access, correction, deletion, objection, restriction, portability, or withdrawal of consent. Most ECHO information is held only on your device, where you control it through the App and iOS. For information you intentionally send to 3Nsofts, contact us through https://3nsofts.com/.

California residents: 3Nsofts does not sell ECHO personal information or share it for cross-context behavioral advertising. ECHO does not knowingly process sensitive personal information to infer characteristics for advertising.

EEA, UK, and similar jurisdictions: when 3Nsofts processes support or download-service information, the basis may be performance of the service, legitimate interests in security and reliability, consent where requested, or compliance with law. You may contact your local data-protection authority.

10. International processing

Infrastructure and service providers may process limited connection or support information in countries other than yours. Applicable safeguards and provider contractual protections govern such processing.

11. Changes

We may update this Policy when ECHO's features, data practices, providers, or legal requirements change. Material changes will be presented in the App or through another appropriate notice. The effective date and version identify the applicable document.
