Terms and Conditions
Notice: Updated terms effective 10th June 2026. This page shows an updated version of our Terms and Conditions, which will take effect on 10th June 2026. Tweak Technologies is providing existing users with at least thirty (30) days' notice prior to that date. Until 10th June 2026 the version of these terms in effect prior to that date continues to apply to existing users.
1. Introduction​
By using tweak browser extension - provided by Tweak Technologies - you confirm your acceptance of, and agree to be bound by, these terms and conditions. These terms and conditions are to be read together with the End-User License Agreement, the Acceptable Use Policy, and the Privacy Policy, each of which is incorporated by reference. In the event of any conflict between these terms and conditions and the End-User License Agreement, the End-User License Agreement shall prevail with respect to the licensing of the Software.
2. Agreement to Terms and Conditions​
This Agreement takes effect on the date on which you first use the tweak browser extension.
3. Definitions​
For the purposes of this Agreement:
- "Software" means the tweak browser extension and any related services made available by Tweak Technologies.
- "Authorized User" means the single, named natural person whose email address is associated with a paid Subscription. The Authorized User is the only individual permitted to install, access, or use the Software under that Subscription.
- "Subscription" means a paid plan that grants one (1) Authorized User the right to use the Software for the duration of that plan.
- "Seat" means the right granted by a single Subscription for one Authorized User to use the Software. Each Seat corresponds to one, and only one, Authorized User.
- "Credentials" means any login email, password, license key, authentication token, session cookie, OAuth token, or other mechanism used to access or activate the Software under a Subscription.
4. Subscription and Seats​
Each Subscription is granted to one Authorized User only. The right to use the Software under a Subscription is personal to the Authorized User and may not be assigned, transferred, shared, or otherwise made available to any other person. If more than one individual within a household, team, or organization requires use of the Software, each such individual must hold their own active Subscription. Tweak Technologies does not grant any right to operate shared, generic, or role-based accounts under a single Subscription.
You represent and warrant that you are the Authorized User of any Subscription registered in your name and that you will not allow any other person to use the Software under your Subscription. You are responsible for keeping your Credentials confidential and for any activity that occurs under your Subscription. Sharing Credentials with any third party, whether inside or outside your organization, is strictly prohibited and constitutes a material breach of this Agreement. Tweak Technologies reserves the right to terminate any Subscription found to be in breach of this clause, immediately and without refund of any fees already paid.
5. Acceptable Use​
Your use of the Software is at all times subject to the Acceptable Use Policy, which sets out, among other things, prohibitions on credential sharing, unauthorized concurrent use, and circumvention of seat or licensing limits. You agree to comply with the Acceptable Use Policy. A breach of the Acceptable Use Policy is a breach of this Agreement.
6. Compliance Verification and Anti-Abuse Monitoring​
Upon reasonable request, you shall provide a written certification, signed by you (or, in the case of an organizational customer, by an authorized representative), confirming that the Software is being used solely by the Authorized User and in full compliance with this Agreement, the End-User License Agreement, and the Acceptable Use Policy. Failure to provide such certification within thirty (30) days of a request, or provision of an incorrect or misleading certification, shall entitle Tweak Technologies to treat the matter as a breach of this Agreement.
You acknowledge and agree that Tweak Technologies may monitor use of the Software and any related services for indicators of abuse, fraud, and breach of this Agreement, including but not limited to concurrent or rapidly alternating sessions from disparate IP addresses, geographies, or devices, anomalous login patterns, multiple distinct device or browser fingerprints associated with a single Subscription, and reuse of a single license key across an unusual number of installations. Telemetry collected for these purposes is used solely for fraud prevention, abuse detection, and verification of compliance with this Agreement, the End-User License Agreement, and the Acceptable Use Policy. It is not used for advertising, for behavioural profiling unrelated to license enforcement, or for sale to third parties. Information collected for these purposes is processed in accordance with our Privacy Policy.
If certification is not provided when requested, or if certification or any other lawful means reveals unauthorized use, you shall be liable for any unpaid Subscription fees corresponding to such unauthorized use, calculated at Tweak Technologies' then-current standard rates, in addition to any other remedy available to Tweak Technologies, including suspension or termination of the affected Subscription without refund.
7. License Duration​
Your right to use the Software continues for so long as you hold an active Subscription and remain in compliance with this Agreement, the End-User License Agreement, and the Acceptable Use Policy. If your Subscription expires, is cancelled, or is terminated for any reason, your right to use the Software ends and you must stop all use of the Software. Termination of any of these agreements terminates the licenses granted under them.
8. Product Communications​
By signing up for a paid Subscription, you agree that we may send you service-related emails at the address linked to your account, including subscription receipts, important product updates, security notices, and notifications of changes to these terms. These are transactional messages and form part of the service. We do not send marketing email unless you separately opt in. You can contact us at [email protected] regarding any communication you receive.
9. Disclaimer​
It is not warranted that tweak browser extension will meet your requirements or that its operation will be uninterrupted or error free. All express and implied warranties or conditions not stated in this Agreement (including without limitation, loss of profits, loss or corruption of data, business interruption or loss of contracts), so far as such exclusion or disclaimer is permitted under the applicable law are excluded and expressly disclaimed. This Agreement does not affect your statutory rights.
10. Warranties and Limitation of Liability​
Tweak Technologies does not give any warranty, guarantee or other term as to the quality, fitness for purpose or otherwise of the software. Tweak Technologies shall not be liable to you by reason of any representation (unless fraudulent), or any implied warranty, condition or other term, or any duty at common law, for any loss of profit or any indirect, special or consequential loss, damage, costs, expenses or other claims (whether caused by Tweak Technologies's negligence or the negligence of its servants or agents or otherwise) which arise out of or in connection with the provision of any goods or services by Tweak Technologies. Tweak Technologies shall not be liable or deemed to be in breach of contract by reason of any delay in performing, or failure to perform, any of its obligations if the delay or failure was due to any cause beyond its reasonable control. Notwithstanding contrary clauses in this Agreement, in the event that Tweak Technologies is deemed liable to you for breach of this Agreement, you agree that Tweak Technologies's liability is limited to the amount actually paid by you for your services or software, which amount calculated in reliance upon this clause. You hereby release Tweak Technologies from any and all obligations, liabilities and claims in excess of this limitation.
11. General Terms and Law​
This Agreement is governed by the laws of the Netherlands, except as otherwise provided by any mandatory applicable law in your jurisdiction, in which case the governing law in relation to all or particular rights and obligations of the parties shall be the laws of your usual place of residence. You acknowledge that no joint venture, partnership, employment, or agency relationship exists between you and Tweak Technologies as a result of your use of these services. You agree not to hold yourself out as a representative, agent or employee of Tweak Technologies. You agree that Tweak Technologies will not be liable by reason of any representation, act or omission to act by you.
12. No Waiver and Severability​
Failure or delay by Tweak Technologies to enforce any right under this Agreement is not a waiver of that right, and a waiver on one occasion is not a waiver on any future occasion. If any provision of this Agreement is held to be invalid or unenforceable by a court of competent jurisdiction, the remaining provisions shall remain in full force and effect, and the invalid or unenforceable provision shall be replaced by an enforceable provision that most closely reflects the original intent of the parties.
13. Right to Modify​
Tweak Technologies reserves the right to change these terms and conditions. If a change is material, Tweak Technologies will provide at least thirty (30) days' notice prior to the new terms taking effect, by in-app notification, by email to the address linked to your Subscription, or by a prominent notice on https://tweak-extension.com. Non-material changes (for example, formatting, typographical corrections, or clarifications that do not adversely affect your rights) may be made at any time. Each time these terms and conditions are changed we will revise the "Effective date" at the bottom of this page. Continued use of the Software after the effective date of any change constitutes your acceptance of the revised terms and conditions.
