SEAL — Terms of Service

Last updated: 25 September 2026 Version: 1.2

1. Parties

These Terms of Service govern the legal relationship between Arkon Technology (“SEAL” or “we”) and the person using the SEAL application (“User” or “you”).

Operator: Arkon Technology
Address: Kızılırmak Mah. Ufuk Üniversitesi Cd. Next Level Loft Ofis, No: 4 Floor: 27 No: 72/76, Söğütözü, Çankaya/Ankara, Türkiye
Corporate email: tech@arkon.cc
Customer support: support@getseal.app
Services: getseal.app website, SEAL iOS and Android mobile apps

2. What SEAL Is

SEAL turns verbal promises and agreements between two people into a digital record. The record is sealed by a single approval: the party whose turn it is approves its latest version. Key actions on a record, including that approval, are signed with the Ed25519 key of the device that performs them, and anyone with the receipt code can see the record’s status, content hash, signature status and audit-chain hashes, as recorded by our server, on a public webpage.

SEAL:

Records who did what, and when.
Adds every signed action to one append-only, hash-chained audit log shared by all agreements, so that altering or removing an entry is detectable.
Once an agreement is in the sealed state, accepts no further changes to its content. If the terms change, the parties create a new record.

SEAL does NOT:

Decide legal validity of agreements.
Bind parties with government-verified identity (e.g. notarial witnessing).
Issue legally certified e-signatures (ETSI/ESHS).

SEAL fills the “here’s a note of what we agreed” need. It can serve as evidence in disputes but final legal effect is at the court’s discretion.

3. Eligibility and Accounts

You must be at least 18 years old to use SEAL.
Each device is assigned a unique identifier. We never link it to a government ID or an email address. If you verify a phone number, that number is associated with your account.
Cryptographic private keys are generated and stored on your device only. We cannot access them.
Because private keys never leave your device, we cannot recover the key from a lost device. If you verified your phone number in SEAL, you can recover your account on a new device by verifying the same number over WhatsApp: the new device gets a new key, the old device’s key is deactivated, and your receipts and drafts return to your archive. Signatures made with the old key stay on record unchanged.

4. Acceptable Use

You may NOT use SEAL for:

Unlawful, violent, misleading, or fraudulent content.
Creating agreements on behalf of others without their consent.
Automated spam or load that disrupts service.
Content infringing intellectual property or copyright.

Violations can result in account or device suspension without notice.

5. Intellectual Property

The app code, brand (“SEAL”, “getseal.app”), logo, UI design, and documentation are property of Arkon Technology.
Content created by users belongs to the users; we process it only to operate the service.

6. Fees and Subscriptions

Creating a new sealed receipt requires a SEAL Plus subscription; eligible new subscribers get their first 3 months free as an introductory offer from the app store (see below). Everything else is free, with or without Plus: opening and reading your receipts, reviewing and approving receipts other people send you, exporting a PDF of any receipt you are a party to, and public verification. Receipts you have already sealed stay accessible and publicly verifiable regardless of your plan.

Plans. SEAL Plus Monthly (renews every month) and SEAL Plus Yearly (renews every year). Both renew automatically.

Introductory offer. Eligible new subscribers get their first 3 months free. Eligibility is determined by the app store, and the offer can be used only once per store account.

Price. The price is shown in the app next to the purchase button, in your local currency, before you confirm. Prices differ by country or region.

How you pay. SEAL Plus is sold only through the app stores’ own in-app purchase systems — Apple In-App Purchase or Google Play Billing. It is not sold on getseal.app, and we never ask for your card details.

Renewal and cancellation. The subscription renews automatically at the end of each period and your store account is charged, unless you cancel at least 24 hours before the current period ends. You can manage or cancel at any time in your store account settings (App Store: Settings -> your name -> Subscriptions; Google Play: Play Store -> Payments and subscriptions). Deleting the app or your SEAL account does not cancel a subscription. Any unused part of a free trial is forfeited when you purchase a subscription.

Refunds. SEAL Plus is sold only through Apple and Google, so refunds are handled under their own policies; we cannot issue those refunds directly. For help with a purchase, contact support@getseal.app.

Apple EULA. For subscriptions purchased through the Apple App Store, Apple’s Standard End User License Agreement also applies: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

If we change prices, existing subscribers will be notified at least 30 days in advance.

7. Availability

We aim for uninterrupted service but:

Maintenance, infrastructure failures, or upstream provider issues (Railway, MongoDB Atlas, Twilio) may cause downtime.
SEAL is not liable for indirect or direct damages arising from such outages.

8. Limitation of Liability

SEAL does not guarantee fulfillment of the promises parties make to each other.
Legal validity of content is subject to local law and court discretion.
To the maximum extent permitted by law, our liability is limited to the amount paid by the User in the given year (zero for free usage).

9. Governing Law

These Terms are governed by the laws of the Republic of Türkiye. Disputes are subject to the Ankara Central Courts and Execution Offices.

10. Changes

We may update these Terms. The current text is published on this page with its last-updated date and version number.
