2. What TeleBloq is
TeleBloq is an app that blocks incoming calls from numbers that aren't saved in your phone's contacts, using Android's call screening feature. The call is declined before it rings, with no notification and without showing up as a missed call on your phone. The app keeps its own history of blocked calls and a list of exceptions that you set.
TeleBloq is not:
- a phone service or a carrier: it doesn't place, answer, record or transmit calls;
- a spam or scam identifier: it doesn't check outside databases of numbers; the only rule is your contacts and your exceptions;
- a fraud protection tool: a call that rings isn't necessarily trustworthy; it only means the number is in your contacts.
3. Requirements
- a phone with Android 10 or later, with active phone service;
- setting TeleBloq as your caller ID & spam app in Android's settings;
- allowing the app to read your contacts;
- a Google account with a valid payment method on Google Play, for the subscription.
There's no iPhone version: Apple's system doesn't let third-party apps decline calls this way.
4. How blocking works and its limits
While blocking is on and your subscription is active, the app applies these rules to each incoming call:
- a number in your phone's contacts: the call rings normally;
- a number in your list of exceptions: the call rings normally;
- a private or unidentified number: the call is declined, unless you turn that option off;
- any other number: the call is declined.
You acknowledge and accept that:
- the app will block legitimate calls from numbers that aren't in your contacts, such as doctors' offices, deliveries, banks, schools and public services; it's up to you to keep your contacts and your list of exceptions up to date;
- calls you make are never affected; the app only acts on calls you receive;
- the app only acts on regular phone calls; calls made through internet apps, such as WhatsApp, don't go through Android's call screening and aren't blocked;
- how the app works depends on Android and on your phone's manufacturer; system updates, manufacturer customizations, battery optimization, or removing the caller ID role can interrupt blocking;
- without the contacts permission, the app lets all calls through, for safety, and says so on the screen;
- the app doesn't replace the system's emergency features or interfere with emergency calls you make.
- if you call 911 or another emergency number, the callback may come from a number that isn't in your contacts; depending on your phone and carrier, Android may let calls through for a few minutes after the emergency call without asking the app, but otherwise the app blocks that callback like any other number, so if you're waiting for a callback, turn blocking off with the switch on the Home screen until it comes in.
5. Who can use it
TeleBloq is for people 18 or older, or minors represented by their parents or legal guardians. By subscribing, you confirm that you have the legal capacity to do so.
6. Subscription, payment and renewal
- using the app requires a subscription, on the monthly plan ($4.99/month) or the annual plan ($49.99/year), sold and charged by Google Play, which shows the price and any applicable tax before you subscribe;
- your subscription renews automatically at the end of each period (month or year, depending on the plan), using the payment method on file with Google Play, until you cancel it;
- the price may change with advance notice from Google Play, under the platform's timelines and conditions, and the change only applies to later renewals;
- blocking only works while your subscription is active; when it expires or is canceled, the app stops blocking calls at the end of the period already paid;
- first-time subscribers may get a 5-day free trial through Google Play (the length Google Play shows before you confirm is the one that applies): your payment method stays on file, nothing is charged during that period, and the first charge happens when the trial ends, unless you cancel before then;
- if we ever offer promotional prices, their terms (the discounted price, how long it lasts, whether there's a free trial, and the price charged afterward) are shown on the subscription screen and on Google Play before you subscribe, and each Google Play account can use a promotional offer only once;
- other free trials, when offered, follow the terms shown when you subscribe.
Payments are processed by Google Play; Natario Labs doesn't have access to your card details. The subscription is validated by RevenueCat, as described in the Privacy Policy.
7. Cancellation and refunds
- you can cancel the renewal at any time on Google Play's subscriptions screen; uninstalling the app doesn't cancel the subscription;
- if you cancel during the Google Play free trial, nothing is charged, and the app keeps working until the trial ends;
- after you cancel, the app keeps working until the end of the period already paid;
- canceling the renewal doesn't, by itself, refund amounts already paid;
- if the law where you live gives you a right to cancel and get your money back within a set period, you can use it within that period (section 15);
- refunds are requested from Google Play, which decides them under its own rules, without limiting the rights the law where you live gives you.
8. Acceptable use
You agree not to:
- use the app for unlawful purposes or to violate the rights of others;
- modify, decompile, reverse engineer or create derivative products from the app, except to the extent the law allows;
- get around the subscription check or distribute modified copies of the app;
- resell, sublicense or commercially exploit the app without permission.
9. Intellectual property
TeleBloq, its brand, icon, interface, code and other elements are protected by intellectual property rights belonging to Natario Labs. You receive a limited, personal, revocable, non-exclusive and non-transferable license to use the app under these Terms. The data that stays on your phone (contacts, exceptions, history) is yours.
10. Personal data protection
Personal data is handled as described in the Privacy Policy, which includes additional information for US residents. If these Terms and the Policy differ on data protection, whichever protects you more applies.
To measure and target our ads, the app includes ad measurement tools from Meta, TikTok and Google, which receive events about the install, app use and the subscription, with the Android advertising ID and without any data from your contacts or your calls, as described in sections 3.5 to 3.7 of the Policy.
11. Availability and changes to the service
Natario Labs works to keep the app running, but doesn't guarantee that it will work without interruptions or errors. The app may be updated, have its features changed, or be discontinued for technical, business or legal reasons, or because of changes to Android or Google Play. Paid features you already purchased will be honored for the paid period, unless that's technically or legally impossible; in that case, we'll refund the proportional amount.
12. Limitation of liability
Natario Labs is liable within the limits of applicable law. To the fullest extent permitted, it isn't liable for:
- legitimate calls blocked because they weren't in your contacts or exceptions, or came from a private number;
- losses from a call you didn't receive because of the settings you chose;
- unwanted calls that ring because the number is in your contacts or exceptions, or because of a failure in Android or on the manufacturer's side;
- Google Play, RevenueCat, Android or your carrier being unavailable or changing;
- use of the app against these Terms;
- acts of God, force majeure or unavoidable outside failures.
Nothing in these Terms excludes rights that the law doesn't allow to be excluded by contract, especially the consumer protection and data protection rights where you live.
13. Communications
Communications about your subscription are sent by Google Play. Communications about these Terms, privacy and support happen through this website or the email you give us when you contact us. You can reach us by WhatsApp +55 21 99607-6777 or email contato@natariolabs.com.br.
14. Changes to these Terms
These Terms may change for legal, technical or business reasons. The current version is the one posted on this page, with the date shown at the top. Significant changes will be announced in the app or on this website and won't affect periods you already paid for.
15. Governing law and jurisdiction
These Terms are governed by the laws of the Federative Republic of Brazil, without limiting the rights that the law where you live gives you. If you have a problem, please contact us first through our support channels.
If you live in the United States, you keep the rights your state's consumer protection laws give you, and you can contact your state attorney general's consumer protection office or the Federal Trade Commission (FTC). You can also go to the courts, and you keep any right the law gives you to bring your case where you live.
