Open-Source Licenses

Version 2026-09-24 · Effective September 24, 2026 · Permanent link to this version

The open-source software and fonts that Fondfully's apps and website include, the licenses they come under, and the notices those licenses ask us to pass on.

The short version

Fondfully is built with the help of open-source software and fonts, and we're grateful to the people who make them. This page lists what our apps and website include, the licenses they come under, and the notices those licenses ask us to pass on to you. It's also in both apps, under Settings › About.

1. Fonts (apps and website)

Fondfully's typefaces are used under the SIL Open Font License, Version 1.1:

  • Bricolage Grotesque. Copyright 2022 The Bricolage Grotesque Project Authors (https://github.com/ateliertriay/bricolage).
  • Figtree. Copyright 2022 The Figtree Project Authors (https://github.com/erikdkennedy/figtree).

Both apps include the fonts together with their license. The website uses smaller subsets of the same fonts, which are covered by the same license.

In summary, the Open Font License lets anyone use, study, modify and redistribute the fonts, including bundled with software, as long as the fonts aren't sold on their own, copies keep the copyright notice and the license, modified versions stay under the same license, and the authors' names aren't used to promote a modified version without their permission. The fonts come with no warranty. This summary isn't the license itself: the full text is at openfontlicense.org, and in both apps under Settings › About › Open-source licenses.

2. The iPhone app

The iPhone app contains no third-party code. Apart from the fonts above, it's built only on Apple's own frameworks, such as SwiftUI, CryptoKit, StoreKit, Vision, VisionKit and WidgetKit, which Apple provides under its own terms. Sign in with Google on iPhone uses Apple's secure web sign-in, not a Google library.

3. The Android app

Open-source components

These components are licensed under the Apache License, Version 2.0, which is reproduced in full in section 7:

  • AndroidX libraries, including Jetpack Compose, Material 3, Navigation, Lifecycle, WorkManager, Glance, Credential Manager, Biometric and ExifInterface, by The Android Open Source Project.
  • The Kotlin standard library, kotlinx.coroutines and kotlinx.serialization, by JetBrains s.r.o. and contributors, and JetBrains Java Annotations, by JetBrains s.r.o.
  • OkHttp and Okio, by Square, Inc.
  • Coil, for showing images, by Coil Contributors, and Accompanist Drawable Painter, by The Android Open Source Project.
  • Guava ListenableFuture, by The Guava Authors, and javax.inject, by The JSR-330 Expert Group.
  • Firebase Components, Firebase Encoders and Android Data Transport, by Google LLC, which ML Kit uses.

This component is licensed under the BSD 3-Clause License, reproduced in section 7:

  • Protocol Buffers, which Glance uses for home screen widgets. Copyright 2008 Google Inc. All rights reserved.

OkHttp includes a compiled copy of the Public Suffix List, which is subject to the Mozilla Public License, Version 2.0. Its source is available at publicsuffix.org.

We checked these components for NOTICE files that the Apache License asks us to pass on. The only one is OkHttp's note about the Public Suffix List, which is quoted in section 7.

Google libraries that aren't open source

These components are provided by Google under Google's own terms rather than an open-source license:

  • Google Play Billing Library, under the Android Software Development Kit License Agreement.
  • Google Play services, including the libraries for signing in with Google and for authorizing Google Drive backup, and the Credential Manager Google ID library, under the Android Software Development Kit License Agreement.
  • ML Kit document scanner and text recognition, under the ML Kit Terms of Service.
  • Google Play In-App Review library, under the Play Core Software Development Kit Terms of Service.

Google's libraries themselves include open-source components from others, such as TensorFlow Lite, Abseil, Protocol Buffers, zlib and libpng, under licenses including Apache 2.0, BSD, MIT, zlib and the Mozilla Public License 2.0. Google supplies the notices for those components with its libraries. How these libraries handle information is explained in our Privacy Policy.

4. Both apps

Both apps keep your vault in SQLite, the public-domain database engine that's built into iOS and Android.

5. Our website

The website's pages and scripts are our own code and use the fonts described in section 1. The only third-party code it loads is Cloudflare Turnstile, the bot check on gift brief claim forms, which Cloudflare provides under its own terms.

6. Our servers

Our servers are built with open-source software too: Hono, Zod, @hono/zod-openapi, @hono/zod-validator, zod-to-openapi, openapi3-ts, jose and @noble/hashes, under the MIT License, and yaml, under the ISC License. Our admin console, which only our team uses, is built with React and React Router, under the MIT License. None of this is distributed to you, but we're glad to credit it.

7. License texts and notices

If you'd like a copy of any license, or think we've missed a credit, write to hello@fondfully.com.

The contents of the NOTICE file are for informational purposes only and do not modify the License. You may add Your own attribution notices within Derivative Works that You distribute, alongside or as an addendum to the NOTICE text from the Work, provided that such additional attribution notices cannot be construed as modifying the License.

5. Submission of Contributions. Unless You explicitly state otherwise, any Contribution intentionally submitted for inclusion in the Work by You to the Licensor shall be under the terms and conditions of this License, without any additional terms or conditions. Notwithstanding the above, nothing herein shall supersede or modify the terms of any separate license agreement you may have executed with Licensor regarding such Contributions.

6. Trademarks. This License does not grant permission to use the trade names, trademarks, service marks, or product names of the Licensor, except as required for reasonable and customary use in describing the origin of the Work and reproducing the content of the NOTICE file.

7. Disclaimer of Warranty. Unless required by applicable law or agreed to in writing, Licensor provides the Work (and each Contributor provides its Contributions) on an "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied, including, without limitation, any warranties or conditions of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A PARTICULAR PURPOSE.

9. Accepting Warranty or Additional Liability.

However, in accepting such obligations, You may act only on Your own behalf and on Your sole responsibility, not on behalf of any other Contributor, and only if You agree to indemnify, defend, and hold each Contributor harmless for any liability incurred by, or claims asserted against, such Contributor by reason of your accepting any such warranty or additional liability.
