Terms of Service

Last Updated: February 2025

1. Acceptance of Terms

By downloading, installing, or using the Calam application ("App"), you agree to be bound by these Terms of Service ("Terms"). If you do not agree to these Terms, do not use the App. These Terms constitute a legally binding agreement between you and Calam.

2. Description of Service

Calam provides Voice over Internet Protocol (VoIP) calling services that allow you to make outbound voice calls over WiFi or mobile data connections.

Important: Calam is not a replacement for traditional mobile or landline phone service. The service requires an active internet connection and may not be available in all locations or at all times.

3. Account Registration

To use Calam, you must:

Be at least 18 years of age
Provide a valid mobile phone number for verification
Maintain the confidentiality of your account credentials
Accept responsibility for all activities under your account
Notify us immediately of any unauthorized access or security breach at support@calam.app

We reserve the right to suspend or terminate accounts that violate these Terms or are used for fraudulent purposes.

4. Payments, Credits, and Billing

Calam operates on a prepaid credit system:

Credits must be purchased before making calls
Call rates vary by destination and are displayed in the App
Credits are non-transferable between accounts
Purchased credits do not expire

Call Billing

Calls are billed in 60-second (one-minute) increments, rounded up to the nearest minute. For example, a call lasting 1 minute and 5 seconds will be billed as 2 minutes.

Rate Changes

Call rates displayed in the App are subject to change without prior notice due to:

Wholesale pricing changes from our telecommunications partners
Currency fluctuations
Regulatory changes in destination countries
Changes to interconnection agreements

New rates apply to all calls made after the change. We recommend checking current rates in the App before making calls. Any credits you have purchased retain their monetary value—only per-minute rates may change.

Data Charges

Calam uses your internet connection (WiFi or mobile data) to make calls. Your mobile carrier may charge for data usage. Please check with your carrier for applicable data rates, especially when roaming internationally.

5. Refund Policy

Unused credits may be refunded within 30 days of purchase, less any credits used. To request a refund, contact us at support@calam.app.

Refund Exceptions

Refunds will not be processed in the following circumstances:

Suspected fraudulent activity on the account
Abuse of the refund policy (e.g., repeated refund requests for same or similar purchases)
Credits used for completed calls, regardless of perceived call quality
Account termination due to Terms of Service violation
Refund requests made more than 30 days after purchase

Quality Issues

If you experience consistently poor call quality, please contact support within 7 days of the issue. We will investigate and may offer credit compensation for documented service failures attributable to our systems. Quality issues caused by your internet connection, device, or third-party networks are not eligible for compensation.

Processing Time

Approved refunds will be processed within 14 business days to the original payment method. Depending on your bank or payment provider, the refund may take additional time to appear in your account.

6. Acceptable Use Policy

You agree not to use Calam to:

Prohibited Communications

Make harassing, threatening, abusive, or defamatory calls
Engage in telemarketing, spam calling, or robocalling
Impersonate any person or entity
Make calls that violate do-not-call registries or similar regulations
Engage in "wangiri" or callback fraud schemes
Make debt collection calls that violate applicable regulations

Commercial and Technical Abuse

Operate call centers or telemarketing operations without prior written authorization from Calam
Resell, redistribute, or commercially exploit the service or minutes/credits to third parties
Use the service through GSM gateways or SIM boxes
Generate artificial traffic or inflate call volumes
Use VPN connections or proxy services in ways that trigger our fraud detection systems (your account may be automatically suspended)
Attempt to bypass geographic restrictions or pricing structures
Use auto-dialers, predictive dialers, or similar technologies without authorization
Interfere with or disrupt our services, servers, or networks
Attempt to circumvent any security measures or access controls

Legal Compliance

Violate any applicable local, national, or international laws or regulations
Use the service for any unlawful purpose
Facilitate or promote illegal activities

Fair Use

Calam is designed for personal, non-commercial use. Accounts showing unusual patterns may be reviewed and suspended pending investigation. Unusual patterns include but are not limited to:

Extremely high call volumes inconsistent with personal use
Calls to a disproportionate number of countries in rapid succession
Calls primarily to premium-rate numbers or known fraud destinations
Patterns consistent with commercial call center operations

Call Recording

Some jurisdictions require all-party consent before recording calls. If you record calls made through Calam, you are solely responsible for complying with all applicable laws regarding recording consent. Calam does not record your calls and is not responsible for any recordings you make.

Violation of this Acceptable Use Policy may result in immediate account suspension or termination without refund.

7. VoIP Restrictions by Country

Legal Restrictions

The use of VoIP services like Calam may be restricted, regulated, or prohibited in certain countries. You are solely responsible for ensuring your use of Calam complies with local laws in your location and the destination you are calling.

Countries and regions known to have VoIP restrictions or bans include (but are not limited to):

United Arab Emirates
Saudi Arabia
Oman
Qatar
Kuwait
China (may require government-approved VPN)
North Korea
Cuba
Egypt (partial restrictions)
Morocco (partial restrictions)

This list may not be current or comprehensive. VoIP regulations change frequently. Please verify local regulations before using Calam in any country.

Carrier Restrictions

Your mobile carrier may:

Throttle or block VoIP traffic on their network
Charge additional fees for data used for VoIP calls
Impose fair use policies that affect VoIP usage
Throttle VoIP traffic, resulting in degraded call quality

Please check with your mobile provider regarding their policies on VoIP applications.

Roaming Considerations

When using Calam while roaming internationally:

Data charges from your mobile carrier may apply and can be significant
VoIP quality depends on local network conditions which may vary
Some countries may block or throttle VoIP traffic at the network level
Hotel and public WiFi networks may block VoIP services

Your Responsibility

Calam is not responsible for any consequences arising from your use of the service in jurisdictions where VoIP is restricted or prohibited. This includes but is not limited to fines, penalties, legal action, or service unavailability.

8. Caller ID Limitations

Important: Calam does not currently support Caller ID (CLI) transmission. When you make calls through Calam:

Your personal phone number will not be displayed to the recipient
Recipients may see "Private Number," "Unknown," or a different number
Recipients will not be able to call you back directly using the displayed number

This limitation exists due to technical and regulatory constraints in international VoIP routing. We may introduce Caller ID features in the future, and any such changes will be communicated through the App.

If recipients need to reach you, you must provide them with your phone number verbally during the call or through other means.

9. Emergency Services

Important: Calam is a VoIP service and cannot be used to call emergency services (such as 999, 112, 911, 000, or any local emergency numbers). Emergency calls require location data and direct network connections that VoIP technology cannot reliably provide.

You must maintain an alternative means of accessing emergency services, such as a traditional landline or mobile phone service. Do not rely on Calam for emergency situations.

10. Service Limitations

Please be aware that:

Calam requires an active internet connection to function
Call quality depends on the speed and stability of your network connection
Calam is not a replacement for traditional phone service
Caller ID is not currently supported (see Section 8)
Service availability may vary by region
We rely on third-party telecommunications providers who may impose additional limitations
Calls to certain destinations may be unavailable or restricted

11. Service Suspension and Interruption

We may suspend, restrict, or interrupt access to the Service without prior notice under the following circumstances:

Scheduled or emergency maintenance
Suspected fraudulent activity or breach of these Terms
Violation of the Acceptable Use Policy
Government or regulatory orders
Network security threats
Non-payment or suspected payment fraud
Force majeure events (see Section 17)

12. Software License

Subject to your compliance with these Terms, we grant you a limited, non-exclusive, non-transferable, revocable license to download, install, and use the App on a device you own or control, solely for personal, non-commercial purposes.

Copy, modify, or distribute the App
Reverse engineer, decompile, or disassemble the App
Rent, lease, lend, sell, or sublicense the App
Remove any proprietary notices or labels

If we cannot resolve the dispute informally, both parties agree that any legal proceedings will be conducted in the courts of Ireland.

23. Governing Law

These Terms shall be governed by and construed in accordance with the laws of Ireland, without regard to its conflict of law provisions. The United Nations Convention on Contracts for the International Sale of Goods shall not apply.

24. Severability

If any provision of these Terms is found to be unenforceable or invalid, that provision shall be limited or eliminated to the minimum extent necessary, and the remaining provisions shall remain in full force and effect.
