Compatibility

Supported environment

Echoknot is delivered as an iOS app. Device and OS availability follows the active App Store distribution configuration for the current release.

Network dependency model

Core data operations are local. AI-assisted actions require network access only when you explicitly trigger generation.

Quick Start

  1. Open Echoknot and set your learning language and level.
  2. Use the plus action to create your first knot.
  3. Add translation, optional usage sentence, and a memory anchor.
  4. Use AI auto-fill when needed (up to 20 free auto-fills per day).
  5. Open Echo chamber and select at least 3 knots in one language.
  6. Generate a story (up to 6 free echo generations per day), then save/favorite high-value echoes.
  7. Use export (JSON/PDF) for backup or migration when needed.

FAQ

How do I edit or delete a knot?

Open a knot from the dashboard list, then use the edit action in knot details. Delete is available in knot details as a destructive action.

Why cannot I generate an echo story?

Echo generation is disabled when fewer than 3 knots are selected, when selected knots use mixed languages, when your daily free echo limit is reached, when provider quota is exhausted, or when network/provider access fails.

What are the current free daily AI limits?

In v1.1, Echoknot allows 20 AI auto-fills per day and 6 echo generations per day. Both counters reset automatically at local midnight.

How do favorites work?

You can favorite saved echoes. Favorites are capped at 5. Unfavorite an item to free space.

Where can I export JSON or PDF?

Use Settings data export buttons, or open the Dashboard export menu in the all-knots area. Both JSON and PDF formats are supported.

What does reset remove?

Reset deletes knots, recent echoes, favorite echoes, and preferences, then restores defaults.

Where do I change theme and language?

In Settings, open Appearance to set theme (Light, Dark, System), app language, and text size.

Does Echoknot sync across devices?

Not in v1.1. The app is local-first in this release. Cloud storage and accounts are future optional items and are not active now.

What data is sent when I use AI features?

Only the text required for the user-triggered action is sent to the configured AI provider. There are no background AI requests by default.

Echoknot App Privacy Policy (EU and US)

Echoknot v1.1 is local-first. TangSpark does not collect, store, sell, or share personal data or personally identifiable information (PII) on TangSpark servers through normal app use.

Last updated: March 4, 2026

What Echoknot stores

  • No account sign-up is required.
  • Knots, echoes, and preferences are stored on your device by default.
  • Always-on cloud sync is not enabled in v1.1.
  • Data export is available as JSON or PDF.

AI processing note

  • AI actions run only when you trigger them.
  • Only required text for that action is sent to the configured AI provider.
  • TangSpark does not use this flow to build personal identity profiles.

For users in EU, EEA, and UK

Under GDPR and UK GDPR, users generally have rights such as access, correction, deletion, restriction, portability, objection, and complaint rights. Because normal usage is local-first and not centrally collected by TangSpark, many controls are available directly in-app via edit, export, and reset actions.

For users in the United States

US state privacy laws (including California) may grant rights to know, correct, delete, and opt out of sale/share of personal information. Echoknot does not sell personal information and is not designed for targeted advertising data sharing in normal app usage.

Privacy requests

Contact support@tang-spark.no and include your region (EU/EEA/UK or US), device model, iOS version, and app version.

Troubleshooting

AI unavailable

  • Confirm internet access, then retry.
  • Check whether the daily free limit has been reached.
  • If daily limit is reached, wait until local midnight reset.
  • Check whether provider quota has been reached.
  • Try a smaller knot selection and regenerate.

Export failed

  • Retry export in the same format.
  • Confirm iOS share sheet appears correctly.
  • Reopen the app and retry.

Echo button disabled

  • Select at least 3 knots.
  • Use knots from one language only.
  • Verify daily echo credits are still available.
  • Verify provider quota is not paused.

Unexpected reset after reinstall

  • Data is local to the device and app installation.
  • Use JSON/PDF export regularly if backup is needed.

Pricing and Roadmap

Echoknot is currently free, with daily AI limits to keep service sustainable.

  • Daily free AI limits: 20 auto-fills and 6 echo generations.
  • Both limits reset at local midnight.
  • Any future pricing changes will be announced before rollout.

Future functionality notes

  • Cloud storage is not available in v1.1.
  • User account system is not available in v1.1.
  • Both are planned as optional extra functionality in future releases.
