Terms of Service

1. Acceptance of Terms

By accessing or using TeraStash (“the Service”), you agree to be bound by these Terms of Service (“Terms”). If you do not agree, do not use the Service. These Terms constitute a legally binding agreement between you and TeraStash.

2. Service Description

TeraStash is an end-to-end encrypted file storage platform. All encryption and decryption operations are performed exclusively on your device (in your browser). TeraStash servers store only opaque, encrypted blobs and cannot access, read, or decrypt the contents of your files. This zero-knowledge architecture means we have no ability to recover your data if you lose your encryption keys or vault password.

3. Eligibility

You must be at least 13 years old to use TeraStash. If you are between 13 and 16 years old and reside in the European Union, you must have parental or guardian consent as required by the GDPR. By using the Service, you represent that you meet these requirements.

4. Account Responsibilities

You are responsible for maintaining the security of your account credentials, including your password, encryption keys, and vault passwords. You agree to provide accurate and complete information when creating your account.

5. Tiers & Billing

5.1 Free Tier

All accounts include a permanent free tier with 20 GB of encrypted storage. No credit card or subscription is required. The free tier is subject to an inactivity policy: if your account has not been accessed for 90 days, we will send weekly email reminders warning that your account is at risk of deletion. After 120 days of inactivity, your account will be marked for deletion with a 3-day grace period. You can cancel the deletion and retain all your data at any time simply by signing in before the grace period expires.

5.2 Free Trial

Paid-tier accounts include a 14-day free trial of all paid features. A valid payment method is required to start the trial; billing is handled by Paddle (Paddle.com Market Limited). You will not be charged during the trial period. At the end of the trial, your subscription will automatically convert to a paid plan unless you cancel before the trial expires. If you cancel, your account will revert to the free tier.

5.3 Paid Plans

Paid storage is available at €3.99 per month per terabyte (Personal plan). Prices may change with 30 days’ notice.

5.4 Payment Processing

All payments are processed by Paddle (Paddle.com Market Limited), our merchant of record. By subscribing, you also agree to Paddle’s terms of service. Paddle handles all billing, invoicing, sales tax, and refund processing.

5.5 Cancellation

You may cancel your subscription at any time through your account settings. Cancellation takes effect at the end of the current billing period. You will retain access to the Service until the end of the period you have already paid for. No refunds are issued for partial billing periods.

5.6 Restricted Accounts

To protect the integrity of the free tier and the shared infrastructure it relies on, we run automated abuse-prevention checks at the point of registration. If one or more signals are detected — including the use of a disposable email domain, a VPN or datacenter IP address, a Tor exit node, or a network ASN associated with hosting infrastructure — your account is automatically assigned a reduced initial storage quota of 1 GB instead of the standard 20 GB.

This is not a penalty or a permanent restriction. Your account remains fully functional and your encryption and privacy guarantees are unchanged. You may request a manual quota review at any time by emailing [email protected]. We will upgrade your quota as soon as possible if no other abuse signals are present. For a detailed explanation of which signals are checked and why, see our Restricted Storage Quota page.

5.7 Over-Quota Enforcement

If your stored data exceeds the quota for your active plan — for example after cancelling a paid subscription or downgrading to a lower tier — your account is immediately placed in read-only mode. You retain full access to download and delete your existing files, but new uploads, syncs, and file creation are blocked until your usage falls within the new limit.

You will receive email reminders and have 3 months from the date of the quota change to bring your usage within the limit by deleting files yourself. Upgrading your plan to one that covers your current storage at any point immediately restores full upload access and cancels any scheduled cleanup.

If the account remains over-quota after 3 months, TeraStash will initiate automated file removal. Files are sorted by last-modified date and removed oldest-first in batches until the account falls within its quota. Before any removal begins, you will receive a final email listing exactly which files will be affected. Files removed through this process are permanently deleted and cannot be recovered.

6. Acceptable Use

You agree not to use TeraStash to store, distribute, or facilitate any of the following:

• Content that violates applicable law, including EU law
• Child sexual abuse material (CSAM)
• Malware, ransomware, exploit kits, or other malicious software
• Content that facilitates terrorism or incites violence
• Harassment, doxxing, stalking, or threatening materials
• Spam distribution or phishing infrastructure
• Circumventing storage quotas, rate limits, or other platform restrictions

7. Zero-Knowledge Enforcement

Due to our zero-knowledge encryption architecture, we cannot inspect or monitor the contents of your files. However, we reserve the right to suspend or terminate accounts based on:

• Valid legal orders or law enforcement requests
• External abuse reports from trusted sources
• Usage patterns consistent with abuse (e.g., excessive bandwidth patterns indicative of malware distribution)
• Violations of these Terms that are detectable without decrypting file contents

8. Intellectual Property

You retain full ownership of your files and data. By using TeraStash, you grant us a limited, non-exclusive license to store your encrypted data solely for the purpose of providing the Service. We claim no ownership or intellectual property rights over your content. The TeraStash name, logo, and platform are our intellectual property.

9. Service Availability

We strive to provide high availability but do not guarantee uninterrupted access. The Service may experience downtime for maintenance, updates, or circumstances beyond our control. We will make reasonable efforts to notify users of planned maintenance in advance.

10. Data Loss & Backups

11. Termination

Either party may terminate this agreement at any time. You may delete your account through your account settings. We may suspend or terminate your account if you violate these Terms, if required by law, or if we discontinue the Service.

Upon termination, your encrypted data will be retained for a 30-day grace period to allow you to download your files. After this grace period, all encrypted data associated with your account will be permanently deleted.

12. Limitation of Liability

To the maximum extent permitted by applicable law, TeraStash’s total liability to you for any claims arising from or related to the Service is limited to the total fees you paid to TeraStash in the 12 months preceding the claim. TeraStash is not liable for any indirect, incidental, special, consequential, or punitive damages, including loss of data, loss of profits, or business interruption, even if advised of the possibility of such damages.

Nothing in these Terms excludes or limits liability for death or personal injury caused by negligence, fraud, or any other liability that cannot be excluded under applicable law.

13. Disclaimer of Warranties

The Service is provided “as is” and “as available” without warranties of any kind, whether express or implied, including but not limited to implied warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the Service will be uninterrupted, error-free, or secure against all threats.

14. Governing Law

These Terms are governed by the laws of the European Union and the member state in which TeraStash is established. Any disputes arising from these Terms or the Service shall be subject to the exclusive jurisdiction of the competent courts in that jurisdiction. If you are a consumer in the EU, you retain the right to bring proceedings in the courts of your member state of residence.

15. Changes to These Terms

We may update these Terms from time to time. For material changes, we will provide at least 30 days’ notice via email or a prominent notice in the Service before the changes take effect. Your continued use of the Service after the changes take effect constitutes acceptance of the updated Terms. If you do not agree with the changes, you should stop using the Service and delete your account.
