This document constitutes a binding agreement between the Entity (User) and Blankline.
These Terms of Service ("Agreement") constitute a legally binding contract between Blankline ("Company," "we," "us") and you ("Customer," "User"). This Agreement governs your access to the Dropstone AI Reasoning Engine, including its autonomous agents, desktop clients, and APIs (collectively, the "Service").
BY CLICKING "I ACCEPT," DOWNLOADING, INSTALLING, ACCESSING, OR USING ANY PART OF THE SERVICE, YOU ACKNOWLEDGE THAT YOU HAVE READ, UNDERSTOOD, AND AGREE TO BE LEGALLY BOUND BY THIS AGREEMENT AND ALL TERMS REFERENCED HEREIN. IF YOU DO NOT AGREE TO THESE TERMS, YOU ARE PROHIBITED FROM ACCESSING OR USING THE SERVICE AND MUST IMMEDIATELY DISCONTINUE ALL USE.
This Agreement is effective as of the date of your first access to the Service and shall remain in effect until terminated in accordance with the provisions herein.
The Service is operated by Blankline, a technology entity organized under the laws of India. While the Service allows for global access, all contractual relationships established herein are domiciled in Chennai, Tamil Nadu, India.
Dropstone is an autonomous artificial intelligence development platform that integrates multiple AI models, autonomous agents, and development tools into a unified desktop application.
The Service integrates with and depends upon third-party artificial intelligence services and APIs, including but not limited to OpenAI, Anthropic, Ollama, Deepseek, and xAI. Your use of the Service constitutes acceptance of the respective terms of service, privacy policies, and usage policies of these third-party providers.
Note: The Service includes autonomous AI agents capable of executing system-level commands. Users assume full responsibility for all autonomous actions taken through the Platform.
You must be at least eighteen (18) years of age to access or use the Service. The Service is not offered to, and may not be used by, anyone under 18. By creating an account you represent that you are 18 or older. If we become aware that an account belongs to someone under 18, we will terminate it and delete the associated data.
The Service automatically collects telemetry data, usage logs, crash reports, and interaction data to optimize AI agent performance, improve Service functionality, and enhance user experience. This data collection is essential for the autonomous learning capabilities of the Platform.
We retain personal data only as long as necessary for the purposes outlined in our Privacy Policy. Upon account termination, we will delete or anonymize personal data within ninety (90) days, except where retention is required for legal purposes.
Subject to your compliance with this Agreement and payment of applicable fees, Blankline grants you a limited, non-exclusive, non-transferable, non-sublicensable, and revocable license during the subscription term.
You expressly agree NOT to:
You acknowledge that Dropstone utilizes non-deterministic, recursive artificial intelligence capable of executing system-level operations (file modification, shell execution, network requests) without continuous human intervention.
You agree to operate the Service solely in environments where you maintain adequate oversight and where data loss or system corruption can be fully recovered. You function as the "Human Supervisor" for all autonomous actions.
BLANKLINE SHALL NOT BE LIABLE FOR ANY DIRECT OR INDIRECT DAMAGES RESULTING FROM ACTIONS TAKEN BY THE AUTONOMOUS AGENT, INCLUDING BUT NOT LIMITED TO: (A) ACCIDENTAL DELETION OF FILES; (B) UNINTENDED NETWORK TRANSMISSIONS; (C) EXECUTION OF ERRONEOUS CODE; OR (D) FINANCIAL LOSS INCURRED VIA API INTERACTIONS.
Individual sandbox. A rolling weekly usage allowance, with access to the Fast and Pro models.
Approximately eight times the weekly allowance of Free. All three production models, browser use, and memory access.
Five times the weekly allowance of Pro, with priority routing during high-traffic periods.
Ten times the weekly allowance of Pro. The highest concurrent task limit we offer.
Current pricing, allowances, and included models for each tier are published at dropstone.io/pricing and form part of this Agreement at the time of your purchase. Enterprise terms are contracted separately.
Paid subscriptions (Pro, Max 5×, and Max 10×) are billed in advance on a recurring basis (monthly or annually, as selected at checkout). Your subscription will automatically renew at the end of each billing cycle at the then-current rate unless you cancel before the renewal date. You authorize us and our payment processor to charge your designated payment method for all applicable fees. Gift subscriptions are one-time purchases and never renew — see Section 8.8.
Every tier, including paid tiers, is subject to a usage allowance measured over a rolling seven-day window that opens on your first request after each reset. No tier is unmetered. When an allowance is exhausted, further requests are declined until the window resets, unless you have enabled wallet fallback and hold a prepaid balance. Allowances are stated at dropstone.io/pricing and are visible in your dashboard at any time. We may adjust allowances on notice; where an adjustment materially reduces the allowance for a tier you have already paid for, it will not take effect until your next renewal.
All subscription fees are final and non-refundable. By subscribing, you acknowledge and agree that no refunds, credits, or proration will be provided for any partial billing periods, unused requests, downgrades, cancellations, or for any other reason, except (a) where a refund is strictly required by mandatory consumer protection laws that cannot be waived by contract, or (b) as expressly provided in Section 8.8 (Gift Subscriptions).
When you upgrade from the Pro tier to the Max tier, the upgrade takes effect immediately and you will be charged for the new tier. ANY FEES ALREADY PAID FOR YOUR EXISTING PRO SUBSCRIPTION ARE NON-REFUNDABLE AND WILL NOT BE CREDITED, REFUNDED, OR PRO-RATED AGAINST THE COST OF THE MAX TIER. You expressly acknowledge that upgrading is a voluntary election and that the remaining value of your prior tier is forfeited upon upgrade. No refund will be issued for the difference between tiers, for any unused portion of the prior tier, or for the upgrade itself.
You may cancel or downgrade your subscription at any time. Cancellations and downgrades take effect at the end of the current billing cycle; you will retain access to your paid features until that date. No refund or credit is issued for the remainder of the billing cycle in which you cancel or downgrade.
We may change subscription pricing at any time. Price changes apply to the next billing cycle following notice to you. Your continued use of the Service after a price change takes effect constitutes acceptance of the new pricing.
All fees are exclusive of applicable taxes, levies, or duties. You are responsible for any such taxes associated with your purchase, except for taxes based on our net income.
Gift subscriptions purchased through our gifting flow are prepaid, one-time purchases and do not automatically renew. They are governed by the Gift Subscription Terms, which form part of these Terms. In summary: a gift must be claimed within twelve (12) months of purchase; a gift sent to a specified email address may only be claimed by an account registered to that address and is not transferable; and if a gift is not claimed before it expires, the amount paid is returned to the purchaser as Dropstone account credit rather than as a refund to the original payment method. Notwithstanding Section 8.3, that account credit is provided as described.
As between the parties, you retain all right, title, and interest in and to: (a) your Input Data (prompts, context files); and (b) the Output generated by the Service (code, logs, artifacts). You may commercialize Output freely.
Blankline retains all rights to the underlying Service, including the "Dropstone" brand, model weights, neural architectures, system prompts, and training methodologies.
We welcome feedback, comments, and suggestions for improvements to the Service ("Feedback"). You grant to us a non-exclusive, worldwide, perpetual, irrevocable, fully-paid, royalty-free, sublicensable, and transferable license under any and all intellectual property rights that you own or control to use, copy, modify, create derivative works based upon, and otherwise exploit the Feedback for any purpose.
The Service may be subject to export control laws. You agree to comply with all applicable export control requirements.
Tier 1, Tier 2, and "God Mode" Team licenses are subject to the direct oversight of the Blankline Research Integrity Council. These licenses are not granted automatically and require a formal governance review to ensure compliance with our core safety and alignment principles.
Recipients of these high-level licenses are bound by the Council’s Integrity Rules, which include mandatory safety audits, restricted deployment environments, and advanced algorithmic transparency requirements.
Full details of the Research Integrity Council’s mandate, ethical framework, and licensing rules are incorporated by reference and can be accessed at: www.blankline.org/governance/research-integrity-council.
In the event of a conflict between these general Terms and the specific license granted by the Research Integrity Council, the Council-issued license shall take legal precedence for that specific enterprise deployment.
You agree to use the Service responsibly and ethically. Prohibited activities include illegal acts, creating malicious software, security violations, harassment, and intellectual property infringement.
We do not guarantee uninterrupted Service. We may release updates, patches, and modifications. Service functionality depends on third-party AI providers and infrastructure.
You may terminate your account at any time. We may suspend or terminate access for violations of these Terms, payment failures, or prohibited activities. Upon termination, data may be deleted in accordance with our policies.
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE SERVICE IS PROVIDED "AS IS," "AS AVAILABLE," AND "WITH ALL FAULTS." BLANKLINE EXPRESSLY DISCLAIMS ALL WARRANTIES, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE.
AI-generated content is probabilistic and may produce unexpected results. You are responsible for reviewing and testing all code before deployment.
You agree to indemnify, defend, and hold harmless Blankline and its proprietor, officers, directors, and employees from and against any and all claims, liabilities, damages, losses, and expenses, including reasonable legal and accounting fees, arising out of or in any way connected with: (a) your access to or use of the Service; (b) your violation of this Agreement; (c) your violation of any third-party right, including intellectual property or privacy rights; or (d) any autonomous actions taken by the Service while under your supervision.
TO THE MAXIMUM EXTENT PERMITTED BY LAW, BLANKLINE'S TOTAL AGGREGATE LIABILITY SHALL NOT EXCEED THE LESSER OF (A) THE TOTAL AMOUNT PAID BY YOU IN THE TWELVE MONTHS PRECEDING THE CLAIM, OR (B) NINE HUNDRED DOLLARS (USD $900).
Blankline specifically disclaims liability for damages arising from autonomous AI agent actions.
