游玩统计 / Game statistics

为提供真实百分位和改进未来评分，系统自动汇总本轮已收录答案的编号、跳过/超时结果、平台及服务器核算的得分。短期随机轮次令牌用于重试去重，最长保存48小时；不使用姓名、账号、设备指纹或应用统计表中的IP。完成一轮后才计入得分分布。完成计入的一轮后，在结果页点击“复制”或“分享”也会按平台各计一次数；不记录分享内容、收件人或联系人，也不代表消息已送达。匿名客户端仍可能重置数据或伪造作答，因此统计单位是提交次数，不是经核验的独立人数。

Recognized answer IDs, skip/timeout outcomes, client platform and server-computed scores aggregate automatically for real percentiles and future rarity calibration. A random round token deduplicates retries and expires after48hours. Application statistics do not store names, accounts, fingerprints or IPs. Only completed counted rounds enter the score distribution. After such a round, a tap on the results Copy or Share button is also counted once per kind and platform; the message, recipients and contacts are never recorded, and a count does not mean a message was delivered. Anonymous clients can still reset data or spoof play; counts measure submissions, not verified unique people.

比个大小同样适用以上规则：上传每题估计的数值（以米为单位）、服务器核算的得分和误差区间，轮次令牌、已完成轮次摘要和匿名汇总的保存期限与下文相同；往期重玩和教程示范不计入统计。

Size It Up follows the same rules: it uploads each numeric guess (in metres), the server-computed points and error ranges under the same token, completed-run summary and anonymous aggregate retention described below; past-puzzle replays and the tutorial demo are never counted.

为防止脚本刷数据，服务器会把网络地址（IPv4 地址或 IPv6 前缀）连同日期做单向哈希，只保留24位截断值，作为当日计数，用于限制同一网络每天新建的轮次和反馈数量。每个截断值对应大量地址，无法还原或识别具体地址，也不与轮次令牌、成绩或反馈关联，最迟于北京时间次日凌晨1点删除。

To stop scripted inflation, the server one-way hashes the network address (IPv4 address or IPv6 prefix) with the date and keeps only a 24-bit truncated value as a same-day counter that limits how many new rounds and reports one network can submit. Each value covers many addresses, cannot be reversed to an address, is never linked to round tokens, scores or reports, and is deleted by 01:00 Beijing time the next day.

若本机保存了前一北京时间日期已完成轮次的有效令牌，开始当日轮次时可一并提交该令牌；两轮均在对应日期完成、且游戏和平台相同时，才计入“已关联次日完成”。前日令牌最多计一次，分母为前日题组全部完成提交（含延迟完成）。无完成时间的历史轮次无法关联。这不是独立玩家留存；清除数据、令牌缺失或过期均无法关联。不新增长期玩家标识，关联及去重记录随原令牌在48小时内到期，匿名合计最多保存13个月。

If this device has a valid token for a round completed on the previous Beijing date, the next session may include that token. A tracked next-day completion is counted only after both rounds finish on their consecutive dates in the same game and platform. Each prior token counts once; the denominator is all completed submissions for the previous dated round, including late completions. Historical sessions without completion timestamps cannot link. This is not unique-person retention. Cleared storage, missing tokens and expired tokens are untracked. No persistent player identifier is added. Links and deduplication expire with the original token within 48 hours; anonymous totals remain for at most 13 months.

真实数据和起步估计 / Observations and starter estimate

真实样本数与得分分布单独列出。同分采用中位百分位，包含自己的已计入成绩。初期另列100份虚拟样本的起步估计，明确标注为估计，不存入真实计数，也不称作真实玩家。小样本结果会波动。答案比例的分母为该题有效答案提交数；跳过和超时另计。已发布题组的答案和分数固定，新数据只用于未来版本的校准与审核。

Real sample counts and histograms are separate. Ties use midrank, including your counted score. A clearly labeled100-observation starter model is an estimate, never stored as real submissions or described as real players. Small samples fluctuate. Answer-choice percentages use valid answer submissions as their denominator; skips/timeouts are separate. Released answers and points remain frozen; observations inform independently reviewed future packs.

漏答反馈 / Missing-answer reports

只有明确确认发送时，才上传指定答案、题号和轮次供编辑核查。请勿填写个人信息。反馈不会立即修改本轮分数。

Free-text missing-answer reports are sent only after explicit confirmation. Do not include personal information. Reports do not immediately change a released score.

来源、平台和托管 / Sources, platforms and hosting

结果页列出来源、许可及收录范围，开放分类可能漏收；英语为同一中文题库的只读翻译。网站、微信和抖音共享游戏数据接口；平台标签目前由客户端声明，不能代替平台身份验证。网站托管商处理网络请求，可能按其政策保存连接日志。测试镜像向游戏统计服务发送上述最少数据，网络不可用时显示连接状态并重试，不把估计冒充真实结果。

Results list source licences and coverage; open categories can omit valid answers. English displays the same Mandarin bank. Web, WeChat and Douyin use shared game-data interfaces; client-declared channel labels do not replace verified platform login. Hosting providers process network requests and may retain connection logs under their policies. The test mirror sends the minimal game statistics above to the canonical service; connection failures stay visible and retry without inventing observed results.

授权创始人可在私有后台查看48小时内的匿名轮次记录（平台、题组日期、开始/完成时间、得分和进度），用于核对提交是否成功。已完成且计入统计的轮次另保留90天摘要：单向轮次编号、平台、题组日期与评分版本、原始得分、开始/完成时间，以及七题已收录答案的编号或跳过/超时结果，用于回查问题和改进未来题组。原始输入不上传。后台不显示可用于游玩的令牌，也不建立跨轮次的长期玩家身份或确认玩家姓名。

Authorized founders can view recent anonymous sessions for up to48hours to reconcile submissions. A separate90-day history of completed counted runs preserves a one-way run reference, platform, round date and scoring edition, original server score, start/finish times, and seven recognized answer IDs or skip/timeout outcomes for troubleshooting and improving future rounds. Raw typing is never uploaded. References are never playable tokens, do not identify a person by name and do not create a persistent identity across rounds.

保存期限 / Retention

可用于游玩的轮次令牌、逐题及复制/分享去重记录和次日关联最长48小时；已完成计入轮次的匿名摘要自完成起保留90天，令牌过期后不能用于验证或继续提交；匿名汇总最长13个月；明确发送的漏答反馈最长90天；防刷计数最长约25小时。自动维护清理到期数据。已删除的历史和缺失的完成时间不会虚构补回。研究来源、已发布题组和编辑审计另行保留，以复现历史成绩。网站免费：不收费、不出售任何内容、不展示广告，也不加载广告代码或第三方追踪脚本。金币只在本机获得和使用，不上传。如果今后加入付费内容或广告，会先更新本页和服务条款，写明相关服务商及其收集的数据。

Playable round tokens, per-question/action deduplication receipts and next-day links expire after48hours. Separate non-authenticating completed-run summaries remain for90days from completion; retaining a summary never extends an expired token or allows further submissions. Anonymous daily aggregates remain for13months and confirmed reports for90days; anti-abuse counters about 25 hours. Scheduled maintenance removes expired data. Deleted history and missing completion timestamps are not invented. Source evidence, releases and editorial audits remain reproducible. The website is free: no charges, nothing for sale, no ads, and no ad code or third-party tracking scripts. Coins are earned and spent on this device and are not uploaded. If anything paid or any ads are ever added, this page and the terms will be updated first to name the providers involved and the data they collect.
