01Who provides the game
Lost Calendars ("the game", "the app") is provided by Barrens Soft (trade name), the independent software studio operating under the name Barrens Soft ("we", "us"), Mihaylovo village 6051, Bulgaria, apps@barrenssoft.com. If a company takes over the game, we will update these terms and tell you in the app.
02These terms
These terms apply when you download and use Lost Calendars. By using the game you accept them. The terms of the store you download it from (Google Play or the Apple App Store) also apply to the download and to payments. How we handle personal data is explained in the Privacy Policy.
If you are under 18, please use the game and make purchases only with the permission of a parent or guardian.
03Your licence
The game, its puzzles, artwork, texts, sounds and code belong to us or to our licensors. We give you a personal, non-exclusive, non-transferable and revocable licence to install the game on devices you own or control and to play it for your own non-commercial use, under these terms and the rules of your store. You may not copy, modify, resell, rent out or redistribute the game or its content, or reverse engineer it, except where the law expressly allows you to.
04What is free
Lost Calendars is free to download and to play. Every puzzle piece, the daily puzzle and the practice can be played without paying. Some actions cost Ink (for example a wrong Seal or a hint), and Ink refills by itself over time. You can also earn extra Ink by solving the daily puzzle or by choosing to watch a rewarded video. The first Seal on a piece is never blocked, even with no Ink left, and thinking time never costs anything.
New chapters and acts open over time on the dates shown in the game.
05Ink and other virtual items
The game uses virtual items: Ink (regular Ink that refills, and saved "bottled" Ink), Explain hint tokens, and boosters such as the Lantern and the Expedition Pass's monthly Field Kit. You can get them by playing, from rewarded videos, or by buying them.
- No cash value: virtual items are a licence to use a feature inside the game. They are not money, have no value outside the game, and cannot be exchanged for money, sold, transferred to another player or moved to another game.
- Using them: items you buy are added to your account in the game once the store confirms the payment. Consumable items are used up when you spend them. A Lantern lasts for 3 hours of playing time.
- Game balance: we may adjust how the game economy works, for example how fast Ink refills or what a hint costs, to keep the game fair and fun. We will not take away bottled Ink, hint tokens or boosters you have bought and not used, except where a purchase is refunded or reversed, or where items were obtained by breaking section 11.
- Keeping them: your bottled Ink and hint tokens are part of your progress backup (section 13). Regular Ink is recalculated on a new device.
06Optional purchases
All purchases are optional and are made through Google Play or the Apple App Store, which process the payment. The prices shown in the store before you confirm a purchase, in your currency and including the taxes the store applies, are the ones that apply. On the date of these terms the US prices are:
| Product | What you get | Type and US price |
|---|---|---|
| Expedition Pass, yearly | No ads at all; an Ink maximum of 10 instead of 5; Ink refills every 10 minutes instead of 20; 3 free Explain hints a day; a monthly Field Kit of 20 bottled Ink. | Auto-renewing subscription, $29.99 a year, with a 7-day free trial for new subscribers |
| Expedition Pass, monthly | The same as the yearly plan. | Auto-renewing subscription, $4.99 a month, no trial |
| Remove Ads | No full-screen ads. Rewarded videos stay available if you want them. | One-time purchase, $4.99 |
| Ink Pot S | 15 bottled Ink | Consumable, $0.99 |
| Ink Pot M | 50 bottled Ink and 5 Explain tokens | Consumable, $2.99 |
| Ink Chest L | 130 bottled Ink and 15 Explain tokens | Consumable, $6.99 |
| Lantern | 3 hours of play in which wrong Seals and "Look here" hints are free | Consumable, $1.99 |
If the Expedition Pass ends, Ink above the regular maximum is moved into bottled Ink, so you lose none of it. Remove Ads and active subscriptions can be restored on a new device signed in to the same store account (Settings → Restore purchases). Consumable items cannot be restored through the store; they travel with your progress backup.
07Subscriptions, renewal and trial
On the yearly plan the paywall states:
"7 days free, then $29.99/year. Renews automatically. Cancel anytime in your store settings – you keep access until the end of the paid period."
On the monthly plan it states: "$4.99/month. Renews automatically. Cancel anytime in your store settings – you keep access until the end of the paid period."
- Automatic renewal: a subscription renews automatically at the end of each period (a year or a month) at the price you agreed to, and your store account is charged, unless you cancel at least 24 hours before the current period ends.
- Free trial: the 7-day free trial is offered only on the yearly plan and only to new subscribers; the store decides who is eligible. If you do not cancel at least 24 hours before the trial ends, it becomes a paid yearly subscription and your store account is charged the yearly price.
- Price changes: if we change a subscription price, Google or Apple will tell you before the change applies, as their rules require. Where those rules or the law require it, the new price applies only if you agree to it; otherwise you can cancel before it applies.
- Payment problems: if a renewal payment fails, the store may retry it for a while. If it still fails, the subscription ends.
08Cancelling and refunds
You cancel a subscription in your store account, not in the game. Uninstalling the game does not cancel a subscription.
- Google Play: open the Play Store app, tap your profile picture, then Payments & subscriptions → Subscriptions → Lost Calendars → Cancel subscription. Google's help: Cancel a subscription on Google Play.
- iPhone and iPad: open Settings, tap your name, then Subscriptions → Lost Calendars → Cancel Subscription. Apple's help: Cancel a subscription from Apple.
When you cancel, the Expedition Pass stays active until the end of the period you have already paid for.
Refunds are handled only by the store you paid, under its refund policy and the law: Google Play (Google Play refund policies) or Apple (request a refund from Apple, or reportaproblem.apple.com). We do not receive your payment and do not issue refunds ourselves. If something went wrong with a purchase, write to us anyway: we will check it, fix any problem in the game, and help you with your request to the store. This does not limit your rights under section 9.
09Your rights as an EU consumer
If you are a consumer in the European Union (the UK has similar rules), mandatory consumer law gives you rights that these terms do not limit:
- Right of withdrawal: for purchases of digital content and services you generally have 14 days to withdraw. For digital content that is delivered immediately, such as Ink, the right can end once delivery starts, if you agreed to that at checkout and acknowledged it. Whether the right applies to your purchase, and how to use it, is shown by the store at checkout. You use it through the store's refund route above, which can also be done on Apple's reportaproblem.apple.com.
- Conformity: under the EU rules on digital content and digital services (Directive (EU) 2019/770) and the national law that implements them, the game and what you pay for must work as described and as you can reasonably expect, and a subscription must do so for the whole period you pay for. If they do not, you are entitled to have the problem fixed and, if it is not fixed within a reasonable time, to a price reduction or to end the contract, as the law provides. Write to us first: most problems we can fix quickly. Where a remedy means paying money back, the payment is made through the store's refund process.
- Updates: we provide the updates needed to keep the game and your purchases working as described, for the periods the law requires.
- Changes to a paid feature: if we change something you pay for in a way that affects you negatively more than in a minor way, we will tell you clearly in advance, and you can end the contract free of charge within 30 days of the change, as the law provides.
10Apple devices
If you play on an iPhone or iPad, Apple's Licensed Application End User License Agreement applies in addition to these terms. If the two differ, Apple's agreement applies to the licence of the app itself, and these terms apply to everything else to the extent the law allows. Apple is not responsible for the game or its support; we are. On Android, Google Play's terms apply to your purchase.
11Fair play
Lost Calendars is built so that every puzzle has one solution you can reach by logic. Please play it as intended. You may not:
- use cheats, bots, modified versions of the app or other tools to get items, progress or purchases you have not earned or paid for;
- manipulate the device clock, the save file or the backup to get Ink, refills or boosters;
- try to get around the purchase system, test or misuse refunds or chargebacks for items you keep using, or exploit bugs on purpose (please report them to us instead);
- try to access other players' data or our cloud services in ways the app does not offer, or interfere with them.
If you seriously break these rules, we may remove items or progress obtained that way and, as a last step and as far as the law allows, end your use of the cloud backup. We will tell you first where we can.
12Ads
The free game shows ads from Google AdMob: optional rewarded videos for extra Ink, and full-screen ads between pieces, never in your first session, never right after a wrong Seal, at most one after every three solved pieces and at least four minutes apart. With the Expedition Pass there are no ads; with Remove Ads there are no full-screen ads. A reward from a video is credited as the game describes, but it is not a purchase. In the EEA, the UK and Switzerland we ask for your consent first. The Privacy Policy explains the details.
13Your progress and the backup
Your progress is saved on your device and backed up to the cloud so you can restore it. We do our best to keep the backup reliable, but it depends on the device, the network and the services we use. Without a linked Google or Apple account, a reinstall can lose your progress if the random ID is not kept (see the Privacy Policy). Link an account in Settings → Account if you want a dependable restore. If progress is lost through our fault, write to us and we will help as far as we can.
14The game's content
The puzzles are built on the ancient Maya calendars, numbers and signs. We research them with care and redraw the signs as our own artwork, but Lost Calendars is a game, not a scholarly reference: some names and texts in puzzles are invented exercises and are marked as such in the game. Please do not rely on the game as a source for academic work.
15Liability
We build Lost Calendars with care, but like any software it may sometimes have errors. We are liable under the applicable law for damage we cause. We are fully liable for intent and gross negligence and for death or personal injury, and nothing in these terms limits liability that the law does not allow to be limited. For ordinary negligence, we are liable for the damage that was foreseeable when you started using the game or made the purchase. We are not liable for interruptions caused by the app stores, Google's or Apple's services, your device or your network, as far as the law allows. Your statutory rights as a consumer, including those in section 9, are not limited by these terms.
16Changes and ending
We may update these terms when the game or the law changes. The effective date at the top shows the current version. If a change is significant, we will tell you in the app before it applies. A change never takes away what you have already paid for during the period you paid for. If you do not agree with a change, you can stop using the game and cancel your subscription before the change applies.
You can stop using Lost Calendars at any time by deleting it; remember to cancel any subscription in your store account, and delete your cloud backup first if you want it gone (Settings → Account). If we ever stop offering the game, we will tell you in the app in advance where we can, and an active subscription will not renew after that.
17Law and complaints
These terms are governed by the law of Bulgaria. If you are a consumer living in another country, you still keep the protection of the mandatory consumer law of your country, and you can bring a claim in the courts of your country.
If you have a complaint, please write to us first at apps@barrenssoft.com; we answer within a few working days. You can also contact a consumer protection authority, such as the consumer authority of your country or, in Bulgaria, the Commission for Consumer Protection. For out-of-court settlement of a dispute you can turn to the conciliation commissions for consumer disputes at the Commission for Consumer Protection, and for a cross-border dispute in the EU to the European Consumer Centre in your country. Taking part in out-of-court settlement is voluntary for both sides and does not affect your right to go to court.
