Terms of Service

Last Updated: September 25, 2026

1. Agreement to Terms#

By downloading, installing, or using the Invisible String mobile application ("App"), you agree to be bound by these Terms of Service ("Terms"). If you do not agree to these Terms, do not use the App.

2. Description of Service#

Invisible String is a mobile application that helps couples discover moments when they may have been in the same place before they met. The App:

  • Scans photo metadata (location and timestamp) from your device's photo library (with your permission)
  • Allows you to securely share location data with a connected partner via nearby connection (Bluetooth/Wi-Fi, iOS only), invite code, or data file
  • Identifies potential "near-miss" encounters in three categories:
    • Chance Encounters: Times you were in the same place on the same day
    • Closest Distance: Your nearest moments ever, regardless of time
    • Closest in Time: Synchronized moments, regardless of distance
  • Presents results in an interactive story format with shareable images

The App is intended for couples who mutually consent to share location history with each other for entertainment purposes. It is not designed for, and must not be used for, surveillance, stalking, or sharing another person's data without their full knowledge and consent.

3. Eligibility#

You must be at least 13 years old to use the App. The App is not directed to children under 13, and we do not knowingly collect personal information from children under 13. If you become aware that a child under 13 has used the App, please contact us.

4. User Accounts and Pairing#

The App does not require account creation. Pairing with your partner can be done via:

  • Nearby Connection (iOS): Direct device-to-device transfer using Bluetooth and Wi-Fi (no data passes through servers)
  • Invite Code (iOS and Android): A 6-character code that lets your partner download your encrypted data through Google Firebase. Codes expire after 12 hours.
  • Data File (iOS and Android): A file you send to your partner yourself, for example by message or email. This file is not encrypted.

You agree to:

  • Pair only with people who have agreed to pair with you
  • Maintain the security of your pairing codes and connections
  • Share data only with a partner who has freely and knowingly consented both to receive your data and to share their own. You confirm that any photos on your device whose metadata you process through the App are your own or were taken with the consent of those involved.

5. Privacy and Data#

Your privacy is important to us. Please review our Privacy Policy, which explains how we collect, use, and protect your information.

Key points:

  • Photo scanning and matching occurs entirely on your device
  • Matching uses only extracted location metadata. Photos you choose to share with your partner are sent directly between your devices and never pass through our servers
  • When using invite code pairing, your location data is encrypted on your device (AES-256-GCM) before upload, held in Google Firebase until the code expires after 12 hours, and then deleted automatically, always within 48 hours
  • When using nearby pairing (iOS), data transfers directly between devices over Apple's encrypted peer-to-peer connection with no cloud involvement
  • Exported data files are not encrypted
  • We use anonymous usage analytics (TelemetryDeck on iOS, Google Analytics for Firebase on Android); your name, photos, and locations are never included
  • You can delete all your data at any time through the App's settings

6. In-App Purchases#

The App offers optional in-app purchases:

  • Story Unlock: Unlocks your near-miss results. The App shows a preview for free, and this one-time purchase reveals up to 5 moments per category.
  • Expansion Pack: Increases the number of results shown per category from 5 to 15, allowing you to see even more near-miss moments.

Purchase terms:

  • All purchases are one-time, non-consumable purchases (buy once, keep forever)
  • All purchases are processed through the Apple App Store or Google Play
  • Prices are displayed in your local currency before purchase
  • Purchases are non-refundable except as required by applicable law or the refund policies of Apple or Google
  • You may restore previous purchases made with the same Apple Account or Google account using the Restore Purchases option in the App
  • Promo codes, where offered, unlock the same features on the device where they are redeemed, have no cash value, and may be withdrawn at any time
  • The Expansion Pack can be enabled or disabled at any time in Settings after purchase

7. Acceptable Use#

You agree NOT to:

  • Use the App for any unlawful purpose
  • Share another person's location data without their consent
  • Attempt to reverse engineer, decompile, or disassemble the App
  • Use the App to stalk, harass, or harm any person
  • Use the App to monitor, track, or surveil any person without their full knowledge and ongoing consent
  • Use the App in connection with intimate partner abuse, harassment, or coercion
  • Share generated story images publicly in a way that reveals another person's location history without their consent
  • Use the App's server or cloud storage features to store, transmit, or share any data other than encrypted data generated by the App for its intended pairing and near-miss functionality
  • Circumvent any security features of the App
  • Use automated systems to access or interact with the App

8. Intellectual Property#

The App and its original content, features, and functionality are owned by us and are protected by international copyright, trademark, and other intellectual property laws.

You retain ownership of your photos and personal data. By using the App, you grant us a limited license to process your data solely for the purpose of providing the App's functionality.

9. User-Generated Content#

Story images and other content you create using the App are yours to share as you wish. However:

We do not guarantee that:

  • The App will be uninterrupted or error-free

  • The App will meet your specific requirements

The App is intended for entertainment. Near-miss results are inferences based on photo metadata that may be inaccurate, missing, or misleading. They may not reflect actual encounters and should not be treated as evidence of any person's actual whereabouts at any time.

11. Limitation of Liability#

TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, INCLUDING BUT NOT LIMITED TO LOSS OF DATA, PROFITS, OR GOODWILL, ARISING OUT OF YOUR USE OF THE APP.

Our total liability for any claim arising from your use of the App shall not exceed the amount you paid for in-app purchases in the twelve (12) months preceding the claim, or $50, whichever is greater.

  • Your use of the App
  • Your violation of these Terms
  • Your violation of any rights of another person or entity

13. Changes to Terms#

We may update these Terms from time to time. We will notify you of any material changes by:

  • Posting the new Terms in the App
  • Updating the "Last Updated" date

Your continued use of the App after changes become effective constitutes acceptance of the revised Terms.

14. Termination#

We may terminate or suspend your access to the App at any time, without prior notice, for conduct that we believe:

  • Violates these Terms
  • Is harmful to other users or third parties
  • Is fraudulent or illegal

You may stop using the App at any time by deleting it from your device.

These Terms shall be governed by and construed in accordance with the laws of the State of California, United States, without regard to its conflict of law provisions.

16. Dispute Resolution#

Any disputes arising from these Terms or your use of the App shall be resolved through binding arbitration in accordance with the rules of the American Arbitration Association. The arbitration shall take place in California, and the arbitrator's decision shall be final and binding.

You agree to waive any right to a jury trial or to participate in a class action lawsuit.

17. Severability#

If any provision of these Terms is found to be unenforceable, the remaining provisions will continue in full force and effect.

18. Entire Agreement#

These Terms, together with our Privacy Policy, constitute the entire agreement between you and us regarding the App and supersede any prior agreements.
