11 +
12 +## License
13 +
14 +Onde is dual-licensed under **MIT** and **Apache 2.0**, at the user's option. This mirrors the licensing model used by the Rust language itself.
15 +
16 +```
17 +SPDX-License-Identifier: MIT OR Apache-2.0
18 +```
19 +
20 +### Why dual license?
21 +
22 +| Concern | MIT alone | MIT OR Apache-2.0 |
23 +|---|---|---|
24 +| Patent grant | ❌ None | ✅ Apache 2.0 includes irrevocable patent grant |
25 +| Enterprise adoption | ⚠️ Legal teams may ask questions | ✅ Widely understood and accepted |
26 +| Rust ecosystem compatibility | ✅ | ✅ |
27 +| Contributor protection | ❌ | ✅ Patent termination clause deters trolling |
28 +| Simplicity | ✅ | ✅ User just picks one |
29 +
30 +### License files
31 +
32 +| File | Contents |
33 +|---|---|
34 +| `LICENSE-MIT` | MIT License, copyright Onde Inference (Splitfire AB) |
35 +| `LICENSE-APACHE` | Apache License 2.0 |
36 +
37 +Never use a single `LICENSE` file for dual-licensed projects. Always maintain both files separately.
38 +
39 +### Cargo.toml declaration
40 +
41 +```toml
42 +license = "MIT OR Apache-2.0"
43 +```
44 +
45 +Use `OR` (uppercase, SPDX standard), not `AND` or `/`. `AND` would mean the user must comply with **both** simultaneously — that is a different and more restrictive claim.
46 +
47 +---
48 +
49 +## Copyright
50 +
51 +The canonical copyright notice for all Onde Inference files is:
52 +
53 +```
54 +Copyright (c) 2026 Onde Inference (Splitfire AB)
55 +```
56 +
57 +- **Onde Inference** — the product/brand name
58 +- **Splitfire AB** — the Swedish legal entity (org. nr. on file)
59 +- Use the year of first publication; do not update the year annually in LICENSE files
60 +
61 +This notice must appear in:
62 +- `LICENSE-MIT`
63 +- `LICENSE-APACHE` (NOTICE file section)
64 +- Any generated SDK packages distributed to registries (crates.io, pub.dev, npm, PyPI)
65 +
66 +---
67 +
68 +## Dependency Licenses
69 +
70 +### Direct dependencies — audit table
71 +
72 +| Crate | License | Notes |
73 +|---|---|---|
74 +| `mistral.rs` (Eric Buehler) | MIT | Must preserve `Copyright (c) 2024 Eric Buehler` |
75 +| `uniffi` | MPL-2.0 | File-level copyleft; compatible with MIT/Apache 2.0 for binary distribution |
76 +| `tokio` | MIT | — |
77 +| `serde` | MIT OR Apache-2.0 | — |
78 +| `anyhow` / `thiserror` | MIT OR Apache-2.0 | — |
79 +| `hf-hub` | Apache-2.0 | — |
80 +| `log` | MIT OR Apache-2.0 | — |
81 +
82 +### MPL-2.0 (`uniffi`) — what it means in practice
83 +
84 +Mozilla Public License 2.0 is **file-level copyleft**:
85 +- You may distribute binaries combining MPL code with MIT/Apache code without restriction.
86 +- If you **modify** MPL-licensed source files, you must make those modifications available.
87 +- As a consumer of `uniffi` (not modifying its internals), **no disclosure obligation applies**.
88 +
89 +### GPL — hard blocker
90 +
91 +Never introduce a GPL-licensed dependency (v2-only in particular). GPL v2 is **incompatible** with Apache 2.0 and would contaminate the entire binary.
92 +
93 +Before adding any new dependency, verify its license with:
94 +
95 +```bash
96 +cargo license --all-features
97 +```
98 +
99 +Acceptable licenses for new dependencies: MIT, Apache-2.0, MIT OR Apache-2.0, ISC, BSD-2-Clause, BSD-3-Clause, MPL-2.0, Unicode-3.0, Zlib.
100 +
101 +---
102 +
103 +## Model Licenses
104 +
105 +**This is the most critical compliance area for downstream users.**
106 +
107 +Onde downloads AI models from HuggingFace at runtime. These models carry their own licenses, entirely separate from Onde's MIT OR Apache-2.0 license. Any application that ships with or downloads these models must comply with the model's license.
108 +
109 +### Current model license table
110 +
111 +| Model | HuggingFace Repo | License | Commercial use |
112 +|---|---|---|---|
113 +| Qwen 2.5 1.5B Instruct | `Qwen/Qwen2.5-1.5B-Instruct` | [Qwen Community License](https://huggingface.co/Qwen/Qwen2.5-1.5B-Instruct/blob/main/LICENSE) | ✅ Allowed with conditions |
114 +| Qwen 2.5 3B Instruct | `Qwen/Qwen2.5-3B-Instruct` | Qwen Community License | ✅ Allowed with conditions |
115 +| Qwen 2.5 Coder 1.5B | `Qwen/Qwen2.5-Coder-1.5B-Instruct` | Qwen Community License | ✅ Allowed with conditions |
116 +| Qwen 2.5 Coder 3B | `Qwen/Qwen2.5-Coder-3B-Instruct` | Qwen Community License | ✅ Allowed with conditions |
117 +| Qwen 2.5 Coder 7B | `Qwen/Qwen2.5-Coder-7B-Instruct` | Qwen Community License | ✅ Allowed with conditions |
118 +
119 +### Key Qwen Community License restrictions
120 +
121 +1. **No training competing models** — you may not use outputs or weights to train a model that competes with Qwen/Alibaba offerings.
122 +2. **Attribution required** — downstream products must acknowledge the use of Qwen models.
123 +3. **No misrepresentation** — you may not claim the model is your own original work.
124 +4. **Threshold clause** — organisations with >100 million monthly active users must obtain a separate commercial licence from Alibaba Cloud.
125 +
126 +### Disclosure obligation
127 +
128 +Onde's README and any SDK README must contain a `## Model Licenses` section that:
129 +- Lists every bundled or downloadable model
130 +- Links to the model's license on HuggingFace
131 +- States that the model license is independent of Onde's own license
132 +
133 +When a new model is added to `src/inference/models.rs`, the model license table in the README **must be updated in the same commit**.
134 +
135 +---
136 +
137 +## Trademark Guidelines
138 +
139 +### Onde Inference brand
140 +
141 +**"Onde Inference"** and the Onde logo (`assets/onde-inference-logo.svg`) are trademarks of Splitfire AB.
142 +
143 +MIT and Apache 2.0 grant code rights only — **neither license grants trademark rights**. This is intentional and protective.
144 +
145 +#### Permitted uses
146 +
147 +- Referring to the project by name: *"built with Onde Inference"*, *"powered by Onde"*
148 +- Linking to the official website or repository
149 +- Stating compatibility: *"compatible with Onde Inference 0.x"*
150 +- Press, editorial, and factual references
151 +
152 +#### Prohibited uses
153 +
154 +- Using "Onde Inference" or the logo as the name of a fork, competing product, or derived SDK
155 +- Implying official endorsement or affiliation without written permission from Splitfire AB
156 +- Using the logo in a way that could cause confusion about the origin of a product
157 +
158 +#### Forks
159 +
160 +A fork of `onde` may use the code freely under MIT OR Apache-2.0 but **must not**:
161 +- Use the "Onde Inference" name as its product name
162 +- Use the Onde logo
163 +- Claim to be the official Onde Inference project
164 +
165 +This is standard open-source brand protection and is consistent with how the Apache Software Foundation, Mozilla, and Rust Foundation handle their trademarks.
166 +
167 +---
168 +
169 +## mistral.rs Fork — Attribution Requirements
170 +
171 +Onde depends on a personal fork of `mistral.rs` by Eric Buehler:
172 +
173 +```toml
174 +mistralrs = { git = "https://github.com/setoelkahfi/mistral.rs",
175 + branch = "fix/all-platform-fixes", ... }
176 +```
177 +
178 +### Obligations
179 +
180 +1. **Preserve the upstream LICENSE** — `mistral.rs/LICENSE` must remain intact and contain `Copyright (c) 2024 Eric Buehler`. Never alter it.
181 +2. **Pin to a commit SHA, not a branch** — branches can be force-pushed or deleted. For any production release, the dependency must be pinned:
182 + ```toml
183 + mistralrs = { git = "https://github.com/setoelkahfi/mistral.rs", rev = "<commit-sha>" }
184 + ```
185 +3. **Upstream-first policy** — fixes that are not Onde-specific should be submitted as PRs to `EricLBuehler/mistral.rs`. Maintaining a long-lived divergent fork creates legal ambiguity about authorship of patches.
186 +4. **NOTICE file** — if Onde ever produces an Apache 2.0 binary distribution (e.g., via PyPI), a `NOTICE` file must include: *"This product includes software developed by Eric Buehler (mistral.rs)."*
187 +
188 +---
189 +
190 +## Distribution Registry Compliance
191 +
192 +### crates.io
193 +
194 +- `license = "MIT OR Apache-2.0"` in `Cargo.toml` ✅
195 +- Both `LICENSE-MIT` and `LICENSE-APACHE` must be present in the repo root
196 +- `readme = "README.md"` must point to a file that contains the `## Model Licenses` section
197 +
198 +### pub.dev (Flutter/Dart)
199 +
200 +- `pubspec.yaml` must declare `license: MIT OR Apache-2.0`
201 +- The `## Model Licenses` section must be present in the published README
202 +- pub.dev displays the license on the package page — verify after each publish
203 +
204 +### Swift Package Manager / onde-swift
205 +
206 +- `onde-swift/README.md` license section must state MIT OR Apache-2.0
207 +- The XCFramework binary is a compiled artifact — it carries Onde's license, mistral.rs attribution, and the model license notice
208 +- The GitHub Release notes for every onde-swift release must include a `## Licenses` section
209 +
210 +### Apple App Store
211 +
212 +- Apple's review guidelines do not restrict MIT/Apache 2.0 licensed code
213 +- The Qwen model license does not conflict with App Store distribution
214 +- Ensure the app's **Privacy Policy** states that inference runs entirely on-device and no user data is transmitted (this is a functional claim Onde enables, not a license issue, but legal teams will ask)
215 +
216 +---
217 +
218 +## Checklist — Adding a New Model
219 +
220 +When adding a new model to `src/inference/models.rs`:
221 +
222 +- [ ] Verify the model's license on HuggingFace before adding
223 +- [ ] Check for the >100M MAU commercial threshold clause
224 +- [ ] Add the model to the `## Model Licenses` table in `onde/README.md`
225 +- [ ] Add the model to the `## Model Licenses` table in `onde-swift/README.md`
226 +- [ ] Add the model to the model license table in this SKILL.md
227 +- [ ] If the model license is more restrictive than Qwen Community License, escalate before shipping
228 +
229 +## Checklist — Adding a New Dependency
230 +
231 +- [ ] Run `cargo license --all-features` and confirm no GPL appears
232 +- [ ] If MPL-2.0: confirm you are not modifying the MPL files
233 +- [ ] If Apache-2.0 only (not MIT): compatible, no action needed
234 +- [ ] If custom/proprietary license: stop and escalate to Splitfire AB legal
235 +
236 +## Checklist — New SDK Release
237 +
238 +- [ ] Both `LICENSE-MIT` and `LICENSE-APACHE` are present
239 +- [ ] `Cargo.toml` / `pubspec.yaml` / `package.json` declare `MIT OR Apache-2.0`
240 +- [ ] README contains `## Model Licenses` section
241 +- [ ] Copyright year and entity (`Onde Inference (Splitfire AB)`) is correct
242 +- [ ] mistral.rs fork dependency is pinned to a commit SHA
243 +- [ ] mistral.rs `LICENSE` (Eric Buehler) is intact and unmodified
244 +
245 +---
246 +
247 +## Quick Reference
248 +
249 +| Question | Answer |
250 +|---|---|
251 +| What license is Onde? | MIT OR Apache-2.0 (user's choice) |
252 +| Who holds the copyright? | Onde Inference (Splitfire AB) |
253 +| Can someone fork Onde and sell it? | Yes, under MIT or Apache 2.0, but they cannot use the "Onde Inference" name or logo |
254 +| Are Qwen models MIT? | No — Qwen Community License. Disclose to users. |
255 +| Can enterprises use Onde commercially? | Yes. Apache 2.0 + Qwen Community License both permit commercial use. |
256 +| Does the patent grant apply? | Yes, under Apache 2.0. Choose Apache 2.0 if patent protection matters to you. |
257 +| Who is Eric Buehler? | Author of mistral.rs. His MIT copyright must be preserved in our fork. |

83 + institute patent litigation against any entity (including a
84 + cross-claim or counterclaim in a lawsuit) alleging that the Work
85 + or a Contribution incorporated within the Work constitutes direct
86 + or contributory patent infringement, then any patent licenses
87 + granted to You under this License for that Work shall terminate
88 + as of the date such litigation is filed.
89 +
90 + 4. Redistribution. You may reproduce and distribute copies of the
91 + Work or Derivative Works thereof in any medium, with or without
92 + modifications, and in Source or Object form, provided that You
93 + meet the following conditions:
94 +
95 + (a) You must give any other recipients of the Work or
96 + Derivative Works a copy of this License; and
97 +
98 + (b) You must cause any modified files to carry prominent notices
99 + stating that You changed the files; and
100 +
101 + (c) You must retain, in the Source form of any Derivative Works
102 + that You distribute, all copyright, patent, trademark, and

105 + the Derivative Works; and
106 +
107 + (d) If the Work includes a "NOTICE" text file as part of its
108 + distribution, then any Derivative Works that You distribute must
109 + include a readable copy of the attribution notices contained

111 + pertain to any part of the Derivative Works, in at least one
112 + of the following places: within a NOTICE text file distributed
113 + as part of the Derivative Works; within the Source form or
114 + documentation, if provided along with the Derivative Works; or,
115 + within a display generated by the Derivative Works, if and
116 + wherever such third-party notices normally appear. The contents
117 + of the NOTICE file are for informational purposes only and
118 + do not modify the License. You may add Your own attribution
119 + notices within Derivative Works that You distribute, alongside
120 + or as an addendum to the NOTICE text from the Work, provided
121 + that such additional attribution notices cannot be construed
122 + as modifying the License.
123 +
124 + You may add Your own copyright statement to Your modifications and
125 + may provide additional or different license terms and conditions
126 + for use, reproduction, or distribution of Your modifications, or

128 + reproduction, and distribution of the Work otherwise complies with
129 + the conditions stated in this License.
130 +
131 + 5. Submission of Contributions. Unless You explicitly state otherwise,
132 + any Contribution intentionally submitted for inclusion in the Work
133 + by You to the Licensor shall be under the terms and conditions of
134 + this License, without any additional terms or conditions.
135 + Notwithstanding the above, nothing herein shall supersede or modify
136 + the terms of any separate license agreement you may have executed
137 + with Licensor regarding such Contributions.
138 +
139 + 6. Trademarks. This License does not grant permission to use the trade
140 + names, trademarks, service marks, or product names of the Licensor,
141 + except as required for reasonable and customary use in describing the
142 + origin of the Work and reproducing the content of the NOTICE file.
143 +
144 + 7. Disclaimer of Warranty. Unless required by applicable law or
145 + agreed to in writing, Licensor provides the Work (and each
146 + Contributor provides its Contributions) on an "AS IS" BASIS,
147 + WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
148 + implied, including, without limitation, any warranties or conditions
149 + of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
150 + PARTICULAR PURPOSE. You are solely responsible for determining the
151 + appropriateness of using or redistributing the Work and assume any
152 + risks associated with Your exercise of permissions under this License.
153 +
154 + 8. Limitation of Liability. In no event and under no legal theory,
155 + whether in tort (including negligence), contract, or otherwise,
156 + unless required by applicable law (such as deliberate and grossly
157 + negligent acts) or agreed to in writing, shall any Contributor be
158 + liable to You for damages, including any direct, indirect, special,
159 + incidental, or consequential damages of any character arising as a
160 + result of this License or out of the use or inability to use the
161 + Work (including but not limited to damages for loss of goodwill,
162 + work stoppage, computer failure or malfunction, or any and all
163 + other commercial damages or losses), even if such Contributor
164 + has been advised of the possibility of such damages.
165 +
166 + 9. Accepting Warranty or Additional Liability. While redistributing
167 + the Work or Derivative Works thereof, You may choose to offer,
168 + and charge a fee for, acceptance of support, warranty, indemnity,
169 + or other liability obligations and/or rights consistent with this
170 + License. However, in accepting such obligations, You may act only
171 + on Your own behalf and on Your sole responsibility, not on behalf
172 + of any other Contributor, and only if You agree to indemnify,
173 + defend, and hold each Contributor harmless for any liability
174 + incurred by, or claims asserted against, such Contributor by reason
175 + of your accepting any such warranty or additional liability.
176 +

37 + Object form, made available under the License, as indicated by a
38 + copyright notice that is included in or attached to the work
39 + (an example is provided in the Appendix below).
40 +
41 + "Derivative Works" shall mean any work, whether in Source or Object
42 + form, that is based on (or derived from) the Work and for which the
43 + editorial revisions, annotations, elaborations, or other modifications
44 + represent, as a whole, an original work of authorship. For the purposes
45 + of this License, Derivative Works shall not include works that remain

47 + the Work and Derivative Works thereof.
48 +
49 + "Contribution" shall mean any work of authorship, including

61 + designated in writing by the copyright owner as "Not a Contribution."
62 +
63 + "Contributor" shall mean Licensor and any individual or Legal Entity
64 + on behalf of whom a Contribution has been received by Licensor and
65 + subsequently incorporated within the Work.
66 +
67 + 2. Grant of Copyright License. Subject to the terms and conditions of
68 + this License, each Contributor hereby grants to You a perpetual,
69 + worldwide, non-exclusive, no-charge, royalty-free, irrevocable
70 + copyright license to reproduce, prepare Derivative Works of,
71 + publicly display, publicly perform, sublicense, and distribute the
72 + Work and such Derivative Works in Source or Object form.
73 +
74 + 3. Grant of Patent License. Subject to the terms and conditions of
75 + this License, each Contributor hereby grants to You a perpetual,
76 + worldwide, non-exclusive, no-charge, royalty-free, irrevocable
77 + (except as stated in this section) patent license to make, have made,
78 + use, offer to sell, sell, import, and otherwise transfer the Work,

80 + by such Contributor that are necessarily infringed by their
81 + Contribution(s) alone or by combination of their Contribution(s)
82 + with the Work to which such Contribution(s) was submitted. If You
83 + institute patent litigation against any entity (including a
84 + cross-claim or counterclaim in a lawsuit) alleging that the Work
85 + or a Contribution incorporated within the Work constitutes direct
86 + or contributory patent infringement, then any patent licenses
87 + granted to You under this License for that Work shall terminate
88 + as of the date such litigation is filed.
89 +
90 + 4. Redistribution. You may reproduce and distribute copies of the
91 + Work or Derivative Works thereof in any medium, with or without
92 + modifications, and in Source or Object form, provided that You
93 + meet the following conditions:
94 +
95 + (a) You must give any other recipients of the Work or
96 + Derivative Works a copy of this License; and
97 +
98 + (b) You must cause any modified files to carry prominent notices
99 + stating that You changed the files; and
100 +
101 + (c) You must retain, in the Source form of any Derivative Works
102 + that You distribute, all copyright, patent, trademark, and
103 + attribution notices from the Source form of the Work,
104 + excluding those notices that do not pertain to any part of
105 + the Derivative Works; and
106 +
107 + (d) If the Work includes a "NOTICE" text file as part of its
108 + distribution, then any Derivative Works that You distribute must
109 + include a readable copy of the attribution notices contained
110 + within such NOTICE file, excluding those notices that do not
111 + pertain to any part of the Derivative Works, in at least one
112 + of the following places: within a NOTICE text file distributed
113 + as part of the Derivative Works; within the Source form or
114 + documentation, if provided along with the Derivative Works; or,
115 + within a display generated by the Derivative Works, if and
116 + wherever such third-party notices normally appear. The contents
117 + of the NOTICE file are for informational purposes only and
118 + do not modify the License. You may add Your own attribution
119 + notices within Derivative Works that You distribute, alongside
120 + or as an addendum to the NOTICE text from the Work, provided
121 + that such additional attribution notices cannot be construed
122 + as modifying the License.
123 +
124 + You may add Your own copyright statement to Your modifications and
125 + may provide additional or different license terms and conditions
126 + for use, reproduction, or distribution of Your modifications, or
127 + for any such Derivative Works as a whole, provided Your use,
128 + reproduction, and distribution of the Work otherwise complies with
129 + the conditions stated in this License.
130 +
131 + 5. Submission of Contributions. Unless You explicitly state otherwise,
132 + any Contribution intentionally submitted for inclusion in the Work
133 + by You to the Licensor shall be under the terms and conditions of
134 + this License, without any additional terms or conditions.
135 + Notwithstanding the above, nothing herein shall supersede or modify
136 + the terms of any separate license agreement you may have executed
137 + with Licensor regarding such Contributions.
138 +
139 + 6. Trademarks. This License does not grant permission to use the trade
140 + names, trademarks, service marks, or product names of the Licensor,
141 + except as required for reasonable and customary use in describing the
142 + origin of the Work and reproducing the content of the NOTICE file.
143 +
144 + 7. Disclaimer of Warranty. Unless required by applicable law or
145 + agreed to in writing, Licensor provides the Work (and each
146 + Contributor provides its Contributions) on an "AS IS" BASIS,
147 + WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
148 + implied, including, without limitation, any warranties or conditions
149 + of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
150 + PARTICULAR PURPOSE. You are solely responsible for determining the
151 + appropriateness of using or redistributing the Work and assume any
152 + risks associated with Your exercise of permissions under this License.
153 +
154 + 8. Limitation of Liability. In no event and under no legal theory,
155 + whether in tort (including negligence), contract, or otherwise,
156 + unless required by applicable law (such as deliberate and grossly
157 + negligent acts) or agreed to in writing, shall any Contributor be
158 + liable to You for damages, including any direct, indirect, special,
159 + incidental, or consequential damages of any character arising as a
160 + result of this License or out of the use or inability to use the
161 + Work (including but not limited to damages for loss of goodwill,
162 + work stoppage, computer failure or malfunction, or any and all
163 + other commercial damages or losses), even if such Contributor
164 + has been advised of the possibility of such damages.
165 +
166 + 9. Accepting Warranty or Additional Liability. While redistributing
167 + the Work or Derivative Works thereof, You may choose to offer,
168 + and charge a fee for, acceptance of support, warranty, indemnity,
169 + or other liability obligations and/or rights consistent with this
170 + License. However, in accepting such obligations, You may act only
171 + on Your own behalf and on Your sole responsibility, not on behalf
172 + of any other Contributor, and only if You agree to indemnify,
173 + defend, and hold each Contributor harmless for any liability
174 + incurred by, or claims asserted against, such Contributor by reason
175 + of your accepting any such warranty or additional liability.
176 +
177 + END OF TERMS AND CONDITIONS
178 +
