Snowfairy AI™ Labs Private Limited — Snowfairy AI™ OS Pen Software
Last updated: August 20, 2026 · Governing law: India · Registered office: Varanasi, Uttar Pradesh
This End User License Agreement ("Agreement") is between you (or, if you're acquiring on behalf of an organization, that organization) and Snowfairy AI™ Labs Private Limited ("Snowfairy", "we", "us") for OS Pen, including its executable files, associated media, and updates (the "Software"). By clicking "I accept the terms in the License Agreement", installing, or using the Software, you agree to be bound by this Agreement. If you do not agree, do not install or use the Software. This Agreement covers only OS Pen — it does not govern our other products or the general snowfairy.ai website, which have their own terms.
Subject to your compliance with this Agreement and payment of any applicable fees, Snowfairy grants you a limited, non-exclusive, non-transferable, revocable license to install and use one copy of the Software on the number of devices permitted by your license tier, for your own personal or internal business use. This license does not transfer any ownership of the Software to you — see Section 6.
Each OS Pen licence is permanently bound to its registered email and one device. Reinstalling OS Pen on the same Windows installation can restore that licence after online sign-in. A different device cannot claim it automatically. At most one free transfer is available only after support verifies a valid documented case and retirement of the old installation. You may buy separate licences using the same email and phone. After the first free transfer, further support-approved transfers cost 50% of the current regular licence plan price. The old device remains blocked for that licence. Internet is required for activation and restoration after reinstall. Offline access follows the signed licence; monthly and yearly plans end on their paid-through date.
If offered, the free trial provides Premium-tier feature access for 14 days from first activation, including Wi-Fi/LAN Collaboration (local-network collaboration between devices on the same WiFi/LAN), a complimentary Premium Beta feature provided at no additional charge — see Section 17. The trial is limited to one trial per verified email account and per physical device (enforced via a one-way hashed device identifier — see our Privacy Policy), and automatically reverts to the Free tier's feature set on expiry with no automatic charge. Creating multiple accounts, resetting/reinstalling Windows, or using virtual machines to obtain additional trials is a violation of this Agreement (see Section 5) and may result in the device being blocked from future trials.
Paid tiers are billed as either a one-time purchase (e.g. the Standard Lifetime launch offer) or a recurring subscription (Standard Yearly, Premium Yearly/Monthly, Basic Yearly), in the currency and amount shown at checkout. If you're in India, your purchase is processed by Razorpay with Snowfairy AI™ Labs as the seller of record. Our order process for purchases outside India is conducted by our online reseller Paddle.com, who will act as Merchant of Record for those transactions once that checkout is live; until then, international customers can purchase by contacting sales@snowfairy.ai. The applicable processor is always shown on the checkout page before you pay. Subscriptions renew automatically at the end of each billing period unless cancelled beforehand from your Account & License window or by contacting support@snowfairy.ai. Refunds are governed by our separate Refund Policy, which takes precedence over this Section wherever it's more favorable to you; where neither the Refund Policy nor applicable consumer protection law grants a refund right, fees already paid are non-refundable.
Except as expressly permitted by this Agreement or applicable law, you may not, and may not permit any third party to:
A violation of this Section is a material breach of this Agreement and may result in immediate license revocation without refund, in addition to any other remedy available to Snowfairy at law.
The Software, including all associated code, design, trademarks ("Snowfairy", "OS Pen", and the Snowfairy AI™ leaf logo), and documentation, is and remains the exclusive property of Snowfairy AI™ Labs Private Limited and its licensors, protected by applicable copyright, trademark, and other intellectual property laws. This Agreement grants you only the limited right to use the Software as described in Section 1 — no other rights are granted. Any ink strokes, annotations, screenshots, or session files you create while using the Software remain entirely your own property; Snowfairy claims no ownership over content you create.
Our collection and use of data in connection with the Software is described in our Privacy Policy, presented as a separate step in the installer and available at any time from within the application. By accepting this Agreement, you also acknowledge the Privacy Policy. In summary: the Software does not transmit your screen content, ink strokes, or session files to our servers unless you explicitly choose to export, save, or share them yourself.
This Agreement is effective from the moment you accept it and continues until terminated. It terminates automatically, without notice, if you breach any term of this Agreement (see Section 5). You may terminate it at any time by uninstalling the Software and, if you wish, requesting account deletion via support@snowfairy.ai. Upon termination, your right to use the Software ends immediately; Sections 5, 6, 10, 11, 12, and 14 survive termination. Termination for breach does not entitle you to a refund of any fees already paid.
Snowfairy may release updates, patches, or new versions of the Software that add, change, or remove features, at its discretion. Some updates may be required for continued use of the Software or continued license validation. Continued use of the Software after an update takes effect constitutes acceptance of any revised terms distributed with that update, subject to Section 15.
The Software is provided "as is" and "as available," without warranty of any kind, express or implied, including but not limited to the implied warranties of merchantability, fitness for a particular purpose, and non-infringement. Snowfairy does not warrant that the Software will be uninterrupted, error-free, or that any defect will be corrected. You are solely responsible for maintaining backups of any content you create with the Software. Nothing in this Section limits any statutory consumer right that cannot lawfully be excluded.
To the maximum extent permitted by applicable law, Snowfairy shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits, data, or goodwill, arising out of or related to your use of (or inability to use) the Software, even if advised of the possibility of such damages. Snowfairy's total aggregate liability under this Agreement shall not exceed the amount you actually paid for the Software in the 12 months preceding the claim — or, if you used the Software under a free or trial tier without paying any fee, INR 1,400 (or its local-currency equivalent, approximately USD 15). Any payment under this cap is subject to Snowfairy's own reasonable investigation confirming the claimed loss actually occurred and was caused by the Software, and is not guaranteed. Nothing in this Section excludes liability that cannot lawfully be excluded, including liability for fraud or wilful misconduct.
You agree to indemnify and hold Snowfairy, its officers, employees, and affiliates harmless from any claim, damage, or expense (including reasonable legal fees) arising out of your breach of this Agreement, your misuse of the Software, or your violation of any law or third-party right through your use of the Software. This does not apply to the extent a claim arises from Snowfairy's own negligence or breach of this Agreement. We reserve the right to pursue legal action, including recovery of our legal costs, against any person who submits a fraudulent claim against us or knowingly makes false statements intended to damage our reputation.
You agree to comply with all applicable export and re-export control laws and regulations in obtaining and using the Software, and confirm you are not located in, or a resident of, any country or on any list subject to applicable trade sanctions that would prohibit your receipt of the Software.
This Agreement is governed by the laws of India, without regard to conflict-of-law principles. Any dispute arising out of or relating to this Agreement shall first be attempted to be resolved through good-faith negotiation by contacting support@snowfairy.ai. If unresolved within 30 days, subject to the carve-out below, the dispute shall be subject to the jurisdiction of the competent courts at Varanasi, Uttar Pradesh, India.
This does not limit any non-waivable right to approach a consumer forum or consumer-protection authority, a data-protection authority, or any other statutory or regulatory body with jurisdiction over a matter. Users outside India retain any dispute-resolution or consumer-protection rights available to them as a matter of mandatory local law that cannot be limited by this Section.
Snowfairy may update this Agreement from time to time, most commonly alongside a Software update. The current version is always available from within the application and on this page, reflecting the "Last updated" date above. Material changes will be highlighted at your next launch of the Software following the update; continued use after that point constitutes acceptance of the revised Agreement. If you do not agree to a revised Agreement, your remedy is to stop using the Software and, if applicable, request a refund under our Refund Policy.
If any provision of this Agreement is held unenforceable, the remaining provisions remain in full force and effect, and the unenforceable provision is replaced by an enforceable one that most closely reflects its original intent. This Agreement, together with our Privacy Policy and Refund Policy, constitutes the entire agreement between you and Snowfairy regarding the Software. You may not assign this Agreement without Snowfairy's prior written consent; Snowfairy may assign this Agreement in connection with a merger, acquisition, or sale of assets. Snowfairy's failure to enforce any right under this Agreement is not a waiver of that right.
Wi-Fi/LAN Collaboration and Creator Recorder are provided to eligible Premium users as complimentary Beta features at no additional charge. Beta features may be incomplete, device-dependent, modified or temporarily unavailable. A feature marked "coming soon" is not part of the current purchased entitlement until it is released and shown as available in the installed application or applicable Order Terms. Nothing in this section limits mandatory consumer rights or remedies under applicable law.
